+<h2 class="h3">HCatalog </h2>
+<div class="section">
+<p>HCatalog is a table management and storage management layer for Hadoop that enables users with different data processing tools &ndash; Pig, MapReduce, Hive, Streaming &ndash; to more easily read and write data on the grid. HCatalog&rsquo;s table abstraction presents users with a relational view of data in the Hadoop distributed file system (HDFS) and ensures that users need not worry about where or in what format their data is stored &ndash; RCFile format, text files, sequence files. </p>
+<p>(Note: In this release, Streaming is not supported. Also, HCatalog supports only writing RCFile formatted files and only reading PigStorage formated text files.)</p>
+<p></p>
+     
+      
+      
+<a name="HCatalog+Architecture"></a>
+<h2 class="h3">HCatalog Architecture</h2>
+<div class="section">
+<p>HCatalog is built on top of the Hive metastore and incorporates components from the Hive DDL. HCatalog provides read and write interfaces for Pig and MapReduce and a command line interface for data definitions.</p>
+<p>(Note: HCatalog notification is not available in this release.)</p>
+<p></p>
+<a name="Interfaces"></a>
+<h3 class="h4">Interfaces</h3>
+<p>The HCatalog interface for Pig &ndash; HCatLoader and HCatStorer &ndash; is an implementation of the Pig load and store interfaces. HCatLoader accepts a table to read data from; you can indicate which partitions to scan by immediately following the load statement with a partition filter statement. HCatStorer accepts a table to write to and a specification of partition keys to create a new partition. Currently HCatStorer only supports writing to one partition. HCatLoader and HCatStorer are implemented on top of HCatInputFormat and HCatOutputFormat respectively </p>
+<p>The HCatalog interface for MapReduce &ndash; HCatInputFormat and HCatOutputFormat &ndash; is an implementation of Hadoop InputFormat and OutputFormat. HCatInputFormat accepts a table to read data from and a selection predicate to indicate which partitions to scan. HCatOutputFormat accepts a table to write to and a specification of partition keys to create a new partition. Currently HCatOutputFormat only supports writing to one partition.</p>
+<p>
+<strong>Note:</strong> Currently there is no Hive-specific interface. Since HCatalog uses Hive's metastore, Hive can read data in HCatalog directly as long as a SerDe for that data already exists. In the future we plan to write a HCatalogSerDe so that users won't need storage-specific SerDes and so that Hive users can write data to HCatalog. Currently, this is supported - if a Hive user writes data in the RCFile format, it is possible to read the data through HCatalog. </p>
+<p>Data is defined using HCatalog's command line interface (CLI). The HCatalog CLI supports most of the DDL portion of Hive's query language, allowing users to create, alter, drop tables, etc. The CLI also supports the data exploration part of the Hive command line, such as SHOW TABLES, DESCRIBE TABLE, etc.</p>
+<a name="Data+Model"></a>
+<h3 class="h4">Data Model</h3>
+<p>HCatalog presents a relational view of data in HDFS. Data is stored in tables and these tables can be placed in databases. Tables can also be hash partitioned on one or more keys; that is, for a given value of a key (or set of keys) there will be one partition that contains all rows with that value (or set of values). For example, if a table is partitioned on date and there are three days of data in the table, there will be three partitions in the table. New partitions can be added to a table, and partitions can be dropped from a table. Partitioned tables have no partitions at create time. Unpartitioned tables effectively have one default partition that must be created at table creation time. There is no guaranteed read consistency when a partition is dropped.</p>
+<p>Partitions contain records. Once a partition is created records cannot be added to it, removed from it, or updated in it. (In the future some ability to integrate changes to a partition will be added.) Partitions are multi-dimensional and not hierarchical. Records are divided into columns. Columns have a name and a datatype. HCatalog supports the same datatypes as Hive. </p>
+</div>
+     
+  
+<a name="Data+Flow+Example"></a>
+<h2 class="h3">Data Flow Example</h2>
+<div class="section">
+<p>This simple data flow example shows how HCatalog is used to move data from the grid into a database. 
+  From the database, the data can then be analyzed using Hive.</p>
+<p>
+<strong>First</strong> Joe in data acquisition uses distcp to get data onto the grid.</p>
+<pre class="code">
+hadoop distcp file:///file.dat hdfs://data/rawevents/20100819/data
+
+hcat "alter table rawevents add partition 20100819 hdfs://data/rawevents/20100819/data"
+</pre>
+<p>
+<strong>Second</strong> Sally in data processing uses Pig to cleanse and prepare the data.</p>
+<p>Without HCatalog, Sally must be manually informed by Joe that data is available, or use Oozie and poll on HDFS.</p>
+<pre class="code">
+A = load '/data/rawevents/20100819/data' as (alpha:int, beta:chararray, &hellip;);
+B = filter A by bot_finder(zeta) = 0;
+&hellip;
+store Z into 'data/processedevents/20100819/data';
+</pre>
+<p>With HCatalog, Oozie will be notified by HCatalog data is available and can then start the Pig job</p>
+<pre class="code">
+A = load 'rawevents' using HCatLoader;
+B = filter A by date = '20100819' and by bot_finder(zeta) = 0;
+&hellip;
+store Z into 'processedevents' using HCatStorer("date=20100819");
+</pre>
+<p>
+<strong>Third</strong> Robert in client management uses Hive to analyze his clients' results.</p>
+<p>Without HCatalog, Robert must alter the table to add the required partition. </p>
+<pre class="code">
+alter table processedevents add partition 20100819 hdfs://data/processedevents/20100819/data
+
+select advertiser_id, count(clicks)
+from processedevents
+where date = '20100819' 
+group by adverstiser_id;
+</pre>
+<p>With HCatalog, Robert does not need to modify the table structure.</p>
+<pre class="code">
+select advertiser_id, count(clicks)
+from processedevents
+where date = &lsquo;20100819&rsquo; 
+group by adverstiser_id;
+</pre>

+<strong>-e</strong>: Usage is -e 'create table mytable(a int);' .... This indicates to HCatalog to treat the following string as DDL command and execute it. </li>

+<strong>Assumptions</strong>
+</p>
+<p>When using the HCatalog CLI, you cannot specify a permission string without read permissions for owner, such as -wxrwxr-x. If such a permission setting is desired, you can use the octal version instead, which in this case would be 375. Also, any other kind of permission string where the owner has read permissions (for example r-x------ or r--r--r--) will work fine.</p>

+<div class="section">
+<p>In earlier versions of HCatalog, to read data users could specify that they were interested in reading from the table and specify various partition key/value combinations to prune, as if specifying a SQL-like where clause. However, to write data the abstraction was not as seamless. We still required users to write out data to the table, partition-by-partition, but these partitions required fine-grained knowledge of which key/value pairs they needed. We required this knowledge in advance, and we required the user to have already grouped the requisite data accordingly before attempting to store. </p>
+<p>The following Pig script illustrates this: </p>
+<pre class="code">
+A = load 'raw' using HCatLoader(); 
+... 
+split Z into for_us if region='us', for_eu if region='eu', for_asia if region='asia'; 
+store for_us into 'processed' using HCatStorer("ds=20110110, region=us"); 
+store for_eu into 'processed' using HCatStorer("ds=20110110, region=eu"); 
+store for_asia into 'processed' using HCatStorer("ds=20110110, region=asia"); 
+</pre>
+<p></p>
+<p>This approach had a major issue. MapReduce programs and Pig scripts needed to be aware of all the possible values of a key, and these values needed to be maintained and/or modified when new values were introduced. With more partitions, scripts began to look cumbersome. And if each partition being written launched a separate HCatalog store, we were increasing the load on the HCatalog server and launching more jobs for the store by a factor of the number of partitions.</p>
+<p>A better approach is to have HCatalog determine all the partitions required from the data being written. This would allow us to simplify the above script into the following: </p>
+<pre class="code">
+A = load 'raw' using HCatLoader(); 
+... 
+store Z into 'processed' using HCatStorer("ds=20110110"); 
+</pre>
+<p>The way dynamic partitioning works is that HCatalog locates partition columns in the data passed to it and uses the data in these columns to split the rows across multiple partitions. (The data passed to HCatalog <strong>must</strong> have a schema that matches the schema of the destination table and hence should always contain partition columns.)  It is important to note that partition columns can&rsquo;t contain null values or the whole process will fail. It is also important note that all partitions created during a single run are part of a transaction and if any part of the process fails none of the partitions will be added to the table.</p>

+<h2 class="h3">Usage with Pig</h2>
+<div class="section">
+<p>Usage from Pig is very simple!  Instead of specifying all keys as one normally does for a store, users can specify the keys that are actually needed. HCatOutputFormat will trigger on dynamic partitioning usage if necessary (if a key value is not specified) and will inspect the data to write it out appropriately.  </p>
+<p>So this statement...</p>
+<pre class="code">
+store A into 'mytable' using HCatStorer("a=1, b=1");
+</pre>
+<p>...is equivalent to any of the following statements, if the data has only values where a=1 and b=1: </p>
+<pre class="code">
+store A into 'mytable' using HCatStorer();
+</pre>
+<pre class="code">
+store A into 'mytable' using HCatStorer("a=1");
+</pre>
+<pre class="code">
+store A into 'mytable' using HCatStorer("b=1");
+</pre>
+<p>On the other hand, if there is data that spans more than one partition, then HCatOutputFormat will automatically figure out how to spray the data appropriately. </p>
+<p>For example, let's say a=1 for all values across our dataset and b takes the value 1 and 2. Then the following statement... </p>
+<pre class="code">
+store A into 'mytable' using HCatStorer();
+</pre>
+<p>...is equivalent to either of these statements: </p>
+<pre class="code">
+store A into 'mytable' using HCatStorer("a=1");
+</pre>
+<pre class="code">
+split A into A1 if b='1', A2 if b='2';
+store A1 into 'mytable' using HCatStorer("a=1, b=1");
+store A2 into 'mytable' using HCatStorer("a=1, b=2");
+</pre>

+<a name="Usage+from+MapReduce"></a>
+<h2 class="h3">Usage from MapReduce</h2>
+<div class="section">
+<p>As with Pig, the only change in dynamic partitioning that a MapReduce programmer sees is that they don't have to specify all the partition key/value combinations.</p>
+<p>A current code example for writing out a specific partition for (a=1,b=1) would go something like this: </p>
+<pre class="code">
+Map&lt;String, String&gt; partitionValues = new HashMap&lt;String, String&gt;();
+partitionValues.put("a", "1");
+partitionValues.put("b", "1");
+HCatTableInfo info = HCatTableInfo.getOutputTableInfo(
+    serverUri, serverKerberosPrincipal, dbName, tblName, partitionValues);
+HCatOutputFormat.setOutput(job, info);
+</pre>
+<p>And to write to multiple partitions, separate jobs will have to be kicked off with each of the above.</p>
+<p>With dynamic partition, we simply specify only as many keys as we know about, or as required. It will figure out the rest of the keys by itself and spray out necessary partitions, being able to create multiple partitions with a single job.</p>

+<a name="Compaction"></a>
+<h2 class="h3">Compaction</h2>
+<div class="section">
+<p>Dynamic partitioning potentially results in a large number of files and more namenode load. To address this issue, we utilize HAR to archive partitions after writing out as part of the HCatOutputCommitter action. Compaction is disabled by default. To enable compaction, use the Hive parameter hive.archive.enabled, specified in the client side hive-site.xml. The current behavior of compaction is to fail the entire job if compaction fails. </p>
