Viraj Bhat commented on HIVE-4524:
----------------------------------
Sushanth, Alan Gates , Olga, Francis and I had a meeting over this at Yahoo!.
We decided that we would pursue with HIVE:4331 but restore the
HCatHBaseStorageHandler for backward compatibility. Let me update the other
HIVE:4331 with Design document for HivePassThroughOutputFormat. Sushanth has
graciously agreed to pursue HIVE:4331

> Make the Hive HBaseStorageHandler work under HCat
> -------------------------------------------------
>
> Key: HIVE-4524
> URL: https://issues.apache.org/jira/browse/HIVE-4524
> Project: Hive
> Issue Type: Bug
> Components: HBase Handler, HCatalog
> Reporter: Sushanth Sowmyan
> Assignee: Sushanth Sowmyan
> Attachments: hbh4.patch
>
>
> Currently, HCatalog has its own HCatHBaseStorageHandler that extends from
> HBaseStorageHandler to allow for StorageHandler support, and does some
> translations, like org.apache.mapred->org.apache.mapreduce wrapping, etc.
> However, this compatibility layer is not complete in functionality as it
> still assumes the underlying OutputFormat is a mapred.OutputFormat
> implementation as opposed to a HiveOutputFormat implementation, and it makes
> assumptions about config property copies that implementations of the
> HiveStorageHandler, such as the HBaseStorageHandler do not do.
> To fix this, we need to improve the ability for HCat to properly load
> native-hive-style StorageHandlers.
> Also, since HCat has its own HBaseStorageHandler and we'd like to not
> maintain two separate HBaseStorageHandlers, the idea is to deprecate HCat's
> storage handler over time, and make sure that hive's HBaseStorageHandler
> works properly from HCat, and over time, have it reach feature parity with
> the HCat one.
