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

Hello, I am deferring this to Hive 3.0 as we are going to cut the first RC and it is not marked as blocker. Please feel free to commit to the branch if this can be resolved before the release.

> It will be difficult for users to switch directly to the HBase metastore.  To allow them to run it in the background while still using the RDBMS implementation we can write a new RawStore implementation that sends write requests to both and reads from just one.
