-----------------------------------

I think that it does not go far enough along to address being able to use any 
generic MR OutputFormat with hive
{quote}
With this StorageHandlers can use generic OFs. The next step would be to make 
SH first class in Hive and migrate all suppported formats to use storage 
handlers. And finally remove HiveOF class.

and I'm not completely certain people have a need for that

Have a need for HOF you mean?

> 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.
