> SerDe to support Teradata Binary Format

>                 Key: HIVE-20225
>                 URL: https://issues.apache.org/jira/browse/HIVE-20225
>             Project: Hive
>          Issue Type: New Feature
>          Components: Serializers/Deserializers
>            Reporter: Lu Li
>            Assignee: Lu Li
>            Priority: Major
>         Attachments: HIVE-20225.1.patch, HIVE-20225.2.patch, HIVE-20225.3.patch
>
>
> When using TPT/BTEQ to export/import Data from Teradata, Teradata will generate/require binary
files based on the schema.
> A Customized SerDe is needed in order to directly read these files from Hive or write
these files in order to load back to TD.
> {code:java}
> CREATE EXTERNAL TABLE `TABLE1`(
> ...)
> PARTITIONED BY (
> ...)
> ROW FORMAT SERDE
>   'org.apache.hadoop.hive.contrib.serde2.TeradataBinarySerde'
> STORED AS INPUTFORMAT
>  'org.apache.hadoop.hive.contrib.fileformat.teradata.TeradataBinaryFileInputFormat'
> OUTPUTFORMAT
>  'org.apache.hadoop.hive.contrib.fileformat.teradata.TeradataBinaryFileOutputFormat'
> LOCATION ...;
> SELECT * FROM `TABLE1`;{code}
> Problem Statement:
> Right now the fast way to export/import data from Teradata is using TPT. However, the
Hive could not directly utilize/generate these binary format because it doesn't have a SerDe
for these files.
> Result:
> Provided with the SerDe, Hive can operate upon/generate the exported Teradata Binary
Format file transparently
