-------------------------
Attachment: HIVE-20225.1.patch
> 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
>
>
> When using TPT/BTEQ to export Data from Teradata, Teradata will export binary
> files based on the schema.
> A Customized SerDe is needed in order to directly read these files from Hive.
> {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 data from Teradata is using TPT. However,
> the Hive could not directly utilize these exported binary format because it
> doesn't have a SerDe for these files.
> Result:
> Provided with the SerDe, Hive can operate upon the exported Teradata Binary
> Format file transparently.
