      Description

      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.

      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`;

      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
