Travis Crawford updated HCATALOG-443:
-------------------------------------
Summary: Use "metadata" Table/Partition classes, and Deserializer when
reading (was: HCatalog should use "metadata" Table/Partition classes except
when serializing)

> Key: HCATALOG-443
> URL: https://issues.apache.org/jira/browse/HCATALOG-443
> Project: HCatalog
> Issue Type: Bug
> Reporter: Travis Crawford
> Assignee: Travis Crawford
>
> This issue is related to HIVE-2950.
> When HCatalog queries the HiveMetaStore it gets back classes in the
> "org.apache.hadoop.hive.metastore.api" package. This represents exactly what
> is stored in the metastore database.
> Hive has companion classes in "org.apache.hadoop.hive.ql.metadata" that
> provide some logic on top of what's stored in the actual database. For
> example:
> * org.apache.hadoop.hive.metastore.api.Table.getCols shows columns explicitly
> stored in the database
> * org.apache.hadoop.hive.ql.metadata.Table.getCols shows columns reported by
> the serde if there are any.
> Except when serializing stuff into the job configuration HCatalog should use
> the "metadata" version of these classes so that the additional logic is
> called.
