             Summary: Initial patch [hbase-metastore branch]
                 Key: HIVE-9453
                 URL: https://issues.apache.org/jira/browse/HIVE-9453
             Project: Hive
          Issue Type: Sub-task
            Reporter: Alan Gates
            Assignee: Alan Gates


This initial patch has several important features:
# HBaseStore, a new implementation of RawStore that stores the data in HBase.
# Subclasses of the thrift metastore objects to remove the massive duplication of data where every partition contains a nearly identical storage descriptor.
# Caches for catalog objects and statistics so that repeated metastore calls don't result in repeated calls against HBase.

Currently this "works" to the point that "load table" and "select" work.  I have not tested any other statements, and I suspect most fail.  There is no security, no authorization, and a no a lot of other things.
