 HAWQ supports data loading from Red Hat Enterprise Linux 5, 6, and 7 and Windows XP client systems. HAWQ Load Tools include both a loader program and a parallel file distribution program.
 
 This topic presents the instructions to install the HAWQ Load Tools on your client machine. It also includes the information necessary to configure HAWQ databases to accept remote client connections.

 The following examples show how to define external data with different protocols. Each `CREATE EXTERNAL TABLE` command can contain only one protocol.
 
 **Note:** When using IPv6, always enclose the numeric IP addresses in square brackets.

 Consider the following scenarios for optimizing your ETL network performance.
 
 -   Allow network traffic to use all ETL host Network Interface Cards (NICs) simultaneously. Run one instance of `gpfdist` on the ETL host, then declare the host name of each NIC in the `LOCATION` clause of your external table definition (see [Creating External Tables - Examples](creating-external-tables-examples.html#topic44)).

 Character encoding systems consist of a code that pairs each character from a character set with something else, such as a sequence of numbers or octets, to facilitate data stransmission and storage. HAWQ supports a variety of character sets, including single-byte character sets such as the ISO 8859 series and multiple-byte character sets such as EUC (Extended UNIX Code), UTF-8, and Mule internal code. Clients can use all supported character sets transparently, but a few are not supported for use within the server as a server-side encoding.
 
 Data files must be in a character encoding recognized by HAWQ. Data files that contain invalid or unsupported encoding sequences encounter errors when loading into HAWQ.

 The output of a shell command or script defines command-based web table data. Specify the command in the `EXECUTE` clause of `CREATE EXTERNAL WEB                 TABLE`. The data is current as of the time the command runs. The `EXECUTE` clause runs the shell command or script on the specified master or virtual segments. The virtual segments run the command in parallel. Scripts must be executable by the gpadmin user and reside in the same location on the master or the hosts of virtual segments.
 
 The command that you specify in the external table definition executes from the database and cannot access environment variables from `.bashrc` or `.profile`. Set environment variables in the `EXECUTE` clause. The following external web table, for example, runs a command on the HAWQ master host:

 The `gpfdist` configuration file uses the YAML 1.1 document format and implements a schema for defining the transformation parameters. The configuration file must be a valid YAML document.
 
 The `gpfdist` program processes the document in order and uses indentation (spaces) to determine the document hierarchy and relationships of the sections to one another. The use of white space is significant. Do not use white space for formatting and do not use tabs.

 The `gp_external_max_segs` server configuration parameter controls the number of virtual segments that can simultaneously access a single `gpfdist` instance. The default is 64. You can set the number of segments such that some segments process external data files and some perform other database processing. Set this parameter in the `hawq-site.xml` file of your master instance.
 
 The number of segments in the `gpfdist` location list specify the minimum number of virtual segments required to serve data to a `gpfdist` external table.

 `CREATE EXTERNAL WEB TABLE` creates a web table definition. Web external tables allow HAWQ to treat dynamic data sources like regular database tables. Because web table data can change as a query runs, the data is not rescannable.
 
 You can define command-based or URL-based web external tables. The definition forms are distinct: you cannot mix command-based and URL-based definitions.

 You can define writable external web tables to send output rows to an application or script. The application must accept an input stream, reside in the same location on all of the HAWQ segment hosts, and be executable by the `gpadmin` user. All segments in the HAWQ system run the application or script, whether or not a segment has output rows to process.
 
 Use `CREATE WRITABLE EXTERNAL WEB TABLE` to define the external table and specify the application or script to run on the segment hosts. Commands execute from within the database and cannot access environment variables (such as `$PATH`). Set environment variables in the `EXECUTE` clause of your writable external table definition.

 Writable external tables that output data to files use the HAWQ parallel file server program, `gpfdist`, or HAWQ Extensions Framework (PXF).
 
 Use the `CREATE WRITABLE EXTERNAL TABLE` command to define the external table and specify the location and format of the output files.

 By default, the escape character is a `"` (double quote) for CSV-formatted files. If you want to use a different escape character, use the `ESCAPE` clause of `COPY`, `CREATE EXTERNAL TABLE` or the `hawq load` control file to declare a different escape character. In cases where your selected escape character is present in your data, you can use it to escape itself.
 
 For example, suppose you have a table with three columns and you want to load the following three fields:

 The output of a shell command or script defines command-based web table data. Specify the command in the `EXECUTE` clause of `CREATE EXTERNAL WEB                 TABLE`. The data is current as of the time the command runs. The `EXECUTE` clause runs the shell command or script on the specified master, and/or segment host or hosts. The command or script must reside on the hosts corresponding to the host(s) defined in the `EXECUTE` clause.
 
 By default, the command is run on segment hosts when active segments have output rows to process. For example, if each segment host runs four primary segment instances that have output rows to process, the command runs four times per segment host. You can optionally limit the number of segment instances that execute the web table command. All segments included in the web table definition in the `ON` clause run the command in parallel.

 This example demonstrates loading a sample IRS Modernized eFile tax return using a Joost STX transformation. The data is in the form of a complex XML file.
 
 The U.S. Internal Revenue Service (IRS) made a significant commitment to XML and specifies its use in its Modernized e-File (MeF) system. In MeF, each tax return is an XML document with a deep hierarchical structure that closely reflects the particular form of the underlying tax code.

 External tables enable accessing external files as if they are regular database tables. They are often used to move data into and out of a HAWQ database.
 
 To create an external table definition, you specify the format of your input files and the location of your external data sources. For information input file formats, see [Formatting Data Files](g-formatting-data-files.html#topic95).

 The default column or field delimiter is the horizontal `TAB` character (`0x09`) for text files and the comma character (`0x2C`) for CSV files. You can declare a single character delimiter using the `DELIMITER` clause of `COPY`, `CREATE                 EXTERNAL TABLE` or the `hawq load` configuration table when you define your data format. The delimiter character must appear between any two data value fields. Do not place a delimiter at the beginning or end of a row. For example, if the pipe character ( | ) is your delimiter:

 When you use the HAWQ tools for loading and unloading data, you must specify how your data is formatted. `COPY`, `CREATE             EXTERNAL TABLE, `and `hawq load` have clauses that allow you to specify how your data is formatted. Data can be delimited text (`TEXT`) or comma separated values (`CSV`) format. External data must be formatted correctly to be read by HAWQ. This topic explains the format of data files expected by HAWQ.

 HAWQ expects rows of data to be separated by the `LF` character (Line feed, `0x0A`), `CR` (Carriage return, `0x0D`), or `CR` followed by `LF` (`CR+LF`, `0x0D 0x0A`). `LF` is the standard newline representation on UNIX or UNIX-like operating systems. Operating systems such as Windows or Mac OS X use `CR` or `CR+LF`. All of these representations of a newline are supported by HAWQ as a row delimiter. For more information, see [Importing and Exporting Fixed Width Data](g-importing-and-exporting-fixed-width-data.html#topic37).

 The `gpfdist://` protocol is used in a URI to reference a running `gpfdist` instance. The `gpfdist` utility serves external data files from a directory on a file host to all HAWQ segments in parallel.
 
 `gpfdist` is located in the `$GPHOME/bin` directory on your HAWQ master host and on each segment host.

 By default, if external table data contains an error, the command fails and no data loads into the target database table. Define the external table with single row error handling to enable loading correctly formatted rows and to isolate data errors in external table data. See [Handling Load Errors](g-handling-load-errors.html#topic55).
 
 The `gpfdist` file server uses the `HTTP` protocol. External table queries that use `LIMIT` end the connection after retrieving the rows, causing an HTTP socket error. If you use `LIMIT` in queries of external tables that use the `gpfdist://` or `http:// protocols`, ignore these errors – data is returned to the database as expected.

 Readable external tables are most commonly used to select data to load into regular database tables. You use the `CREATE TABLE AS SELECT` or `INSERT                 INTO `commands to query the external table data. By default, if the data contains an error, the entire command fails and the data is not loaded into the target database table.
 
 The `SEGMENT REJECT LIMIT` clause allows you to isolate format errors in external table data and to continue loading correctly formatted rows. Use `SEGMENT REJECT LIMIT `to set an error threshold, specifying the reject limit `count` as number of `ROWS` (the default) or as a `PERCENT` of total rows (1-100).

 If a CSV file contains invalid formatting, the *rawdata* field in the error table can contain several combined rows. For example, if a closing quote for a specific field is missing, all the following newlines are treated as embedded newlines. When this happens, HAWQ stops parsing a row when it reaches 64K, puts that 64K of data into the error table as a single row, resets the quote flag, and continues. If this happens three times during load processing, the load file is considered invalid and the entire load fails with the message "`rejected ` `N` ` or more rows`". See [Escaping in CSV Formatted Files](g-escaping-in-csv-formatted-files.html#topic101) for more information on the correct use of quotes in CSV files.

 The topics in this section describe methods for loading and writing data into and out of HAWQ, and how to format data files. It also covers registering HDFS files and folders directly into HAWQ internal tables.
 
 HAWQ supports high-performance parallel data loading and unloading, and for smaller amounts of data, single file, non-parallel data import and export.

 `COPY FROM` copies data from a file or standard input into a table and appends the data to the table contents. `COPY` is non-parallel: data is loaded in a single process using the HAWQ master instance. Using `COPY` is only recommended for very small data files.
 
 The `COPY` source file must be accessible to the master host. Specify the `COPY` source file name relative to the master host location.

 The HAWQ `hawq load` utility loads data using readable external tables and the HAWQ parallel file server ( `gpfdist` or `gpfdists`). It handles parallel file-based external table setup and allows users to configure their data format, external table definition, and `gpfdist` or `gpfdists` setup in a single configuration file.

 Use the following tip to help optimize your data load and subsequent query performance.
 
 -   Run `ANALYZE` after loading data. If you significantly altered the data in a table, run `ANALYZE` or `VACUUM                     ANALYZE` (system catalog tables only) to update table statistics for the query optimizer. Current statistics ensure that the optimizer makes the best decisions during query planning and avoids poor performance due to inaccurate or nonexistent statistics.

 The `hawq register` utility loads and registers HDFS data files or folders into HAWQ internal tables. Files can be read directly, rather than having to be copied or loaded, resulting in higher performance and more efficient transaction processing.
 
 Data from the file or directory specified by \<hdfsfilepath\> is loaded into the appropriate HAWQ table directory in HDFS and the utility updates the corresponding HAWQ metadata for the files. Either AO or Parquet-formatted tables in HDFS can be loaded into a corresponding table in HAWQ.

 `NULL` represents an unknown piece of data in a column or field. Within your data files you can designate a string to represent null values. The default string is `\N` (backslash-N) in `TEXT` mode, or an empty value with no quotations in `CSV` mode. You can also declare a different string using the `NULL` clause of `COPY`, `CREATE EXTERNAL                 TABLE `or the `hawq load` control file when defining your data format. For example, you can use an empty string if you do not want to distinguish nulls from empty strings. When using the HAWQ loading tools, any data item that matches the designated null string is considered a null value.

 By default, `COPY` stops an operation at the first error: if the data contains an error, the operation fails and no data loads. If you run `COPY                 FROM` in *single row error isolation mode*, HAWQ skips rows that contain format errors and loads properly formatted rows. Single row error isolation mode applies only to rows in the input file that contain format errors. If the data contains a contraint error such as violation of a `NOT NULL` or `CHECK` constraint, the operation fails and no data loads.
 
 Specifying `SEGMENT REJECT LIMIT` runs the `COPY` operation in single row error isolation mode. Specify the acceptable number of error rows on each segment, after which the entire `COPY FROM` operation fails and no rows load. The error row count is for each HAWQ segment, not for the entire load operation.

 Use one of the following approaches to transform the data with `gpfdist`.
 
 -   `GPLOAD` supports only input transformations, but is easier to implement in many cases.

 To transform data using the `GPLOAD ` control file, you must specify both the file name for the `TRANSFORM_CONFIG` file and the name of the `TRANSFORM` operation in the `INPUT` section of the `GPLOAD` control file.
 
 -   `TRANSFORM_CONFIG `specifies the name of the `gpfdist` configuration file.

 Specify the transformation in the `CREATE EXTERNAL TABLE` definition's `LOCATION` clause. For example, the transform is shown in bold in the following command. (Run `gpfdist` first, using the command `gpfdist             -c config.yaml`).
