> 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
