Sushanth Sowmyan commented on HIVE-4331: ---------------------------------------- As an update, after a bit of thinking about how backward compatibility should, I have no further issues or comments on the HCatalog side of the patch, I'm +1 on it. There is work to be done there, but not relevant directly to this patch. It belongs more into an addendum for HIVE-5233 than it does over here. I'm +1 on the HCat side (barring some minor spacing issues, which I can fix before committing) > 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, > HIVE-4331.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. -- This message is automatically generated by JIRA.
