Travis Crawford updated HCATALOG-443:
-------------------------------------
Attachment: HCATALOG-443_api_to_metadata_deserializer.4.patch
Updated patch to allow conversion of boolean fields to integer. This is enabled
by setting the field schema to integer. By default booleans are treated as
boolean.
This is useful for integration with pre-boolean-support pig environments.
> Serde-reported schema support, enums as strings, misc fixes

> 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.
