facilitate HBase bulk loads from Hive
-------------------------------------
Key: HIVE-1295
URL: https://issues.apache.org/jira/browse/HIVE-1295
Project: Hadoop Hive
Issue Type: Improvement
Components: HBase Handler
Affects Versions: 0.6.0
Reporter: John Sichi
Assignee: John Sichi
Fix For: 0.6.0
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.
