--------------------------------------
Hi Sushanth,
Thanks for your feedback. Can we agree to commit the patches as is with the
understanding that we will address the remaining concerns after wards. The
patches are large and we already spend a lot of time adjusting andre-basing
them. Given that things change pretty rapidly, we just want to make sure we do
not need to rebase yet again.
> 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: HBase Handler, HCatalog
> Affects Versions: 0.12.0
> Reporter: Ashutosh Chauhan
> Assignee: Viraj Bhat
> Fix For: 0.12.0

> Attachments: HIVE4331_07-17.patch, hive4331hcatrebase.patch,

> 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.
