HBase supports a bulk load procedure:
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.
