> 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.
