      Description

      HBase supports a bulk load procedure:

      http://hadoop.apache.org/hbase/docs/r0.20.2/api/org/apache/hadoop/hbase/mapreduce/package-summary.html#bulk

      We would like to add support to Hive so that users can bulk load HBase from Hive without having to write any map/reduce code.

      Ideally, this could be done with a single INSERT statement targeting the HBase storage handler (with an option set to request bulk load instead of row-level inserts).

      However, that will take a lot of work, so this JIRA is a first step to allow the bulk load files to be prepared inside of Hive via a sequence of SQL statements and then pushed into HBase via the loadtable.rb script.

      Note that until HBASE-1861 is implemented, the bulk load target table can only have a single column family.
