Sushanth Sowmyan commented on HIVE-4331:
----------------------------------------
I would love to see SH become a first class entry in hive, and HOF be a kind of
SH, leading to its eventual removal. That's precisely what my long-term goal
for this is.
> and I'm not completely certain people have a need for that
By this bit, I meant that I wasn't sure people had a need for doing away with
HOF (other than for code-cleanliness, which is why I would like to see it gone)
being able to use any generic OF with hive - most of the usecases of
traditional M/R OFs are already covered by hive, or for newer formats being
developed, the OF writer winds up making changes so that it is hive compatible,
such as with orc, or with the HBase SH. So unless there were a major push to
see a BlahOutputFormat that is widely used, but was not already usable from
within Hive, I don't see there being a necessity case for a change in hive that
I want. :)

> 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.
