Sushanth Sowmyan commented on HIVE-4331:
----------------------------------------
I left some more comments on the hive patch phabricator review. Apart from a
couple of minor code-style comments, the majority of my feeling about this is
that I'm okay with what HivePTOF is doing, and it's a good first step, and I
will +1 it, but I think that it does not go far enough along to address being
able to use any generic MR OutputFormat with hive. That said, I agree that that
would not really be possible unless we plumb out how HiveOutputFormat is used
itself, and I'm not completely certain people have a need for that.
> Integrated StorageHandler for Hive and HCat using the HiveStorageHandler

> Key: HIVE-4331
> URL: https://issues.apache.org/jira/browse/HIVE-4331
> Project: Hive
> Issue Type: Task
> Components: HCatalog
> Affects Versions: 0.11.0, 0.12.0
> Reporter: Ashutosh Chauhan
> Assignee: Viraj Bhat
> Attachments: HIVE4331_07-17.patch, StorageHandlerDesign_HIVE4331.pdf

>
> 1) Deprecate the HCatHBaseStorageHandler and "RevisionManager" from HCatalog.
> These will now continue to function but internally they will use the
> "DefaultStorageHandler" from Hive. They will be removed in future release of
> Hive.
> 2) Design a HivePassThroughFormat so that any new StorageHandler in Hive will
> bypass the HiveOutputFormat. We will use this class in Hive's
> "HBaseStorageHandler" instead of the "HiveHBaseTableOutputFormat".
> 3) Write new unit tests in the HCat's "storagehandler" so that systems such
> as Pig and Map Reduce can use the Hive's "HBaseStorageHandler" instead of the
> "HCatHBaseStorageHandler".
> 4) Make sure all the old and new unit tests pass without backward
> compatibility (except known issues as described in the Design Document).
> 5) Replace all instances of the HCat source code, which point to
> "HCatStorageHandler" to use the"HiveStorageHandler" including the
> "FosterStorageHandler".
> I have attached the design document for the same and will attach a patch to
> this Jira.
