Subject [jira] [Commented] (HIVE-6584) Add HiveHBaseTableSnapshotInputFormat
Date Wed, 16 Jul 2014 17:00:10 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14063719#comment-14063719

Nick Dimiduk commented on HIVE-6584:
------------------------------------

Ouch. Most of these tests run/pass for me locally. Will investigate further. I'm also curious
why the {{explain}} commands in {{hbase_handler_snapshot.q}} are not including the Input/OutputFormats.

[~sushanth], [~ashutoshc] any ideas on this latter issue?

> HBASE-8369 provided mapreduce support for reading from HBase table snapsopts. This allows
a MR job to consume a stable, read-only view of an HBase table directly off of HDFS. Bypassing
the online region server API provides a nice performance boost for the full scan. HBASE-10642
is backporting that feature to 0.94/0.96 and also adding a {{mapred}} implementation. Once
that's available, we should add an input format. A follow-on patch could work out how to integrate
this functionality into the StorageHandler, similar to how HIVE-6473 integrates the HFileOutputFormat
into existing table definitions.
