Nick Dimiduk updated HIVE-6584: ------------------------------- Release Note: Hive can now execute queries against HBase table snapshots. This feature is available for any table defined using the HBaseStorageHandler. It requires at least HBase 0.98.3. To query against a snapshot instead of the online table, specify the snapshot name via hive.hbase.snapshot.name. The snapshot will be restored into a unique directory under /tmp. This location can be overridden by setting a path via hive.hbase.snapshot.restoredir. > Add HiveHBaseTableSnapshotInputFormat > ------------------------------------- > > Key: HIVE-6584 > URL: https://issues.apache.org/jira/browse/HIVE-6584 > Project: Hive > Issue Type: Improvement > Components: HBase Handler > Reporter: Nick Dimiduk > Assignee: Nick Dimiduk > Labels: TODOC14 > Fix For: 0.14.0 > > Attachments: HIVE-6584.0.patch, HIVE-6584.1.patch, > HIVE-6584.10.patch, HIVE-6584.11.patch, HIVE-6584.12.patch, > HIVE-6584.13.patch, HIVE-6584.14.patch, HIVE-6584.2.patch, HIVE-6584.3.patch, > HIVE-6584.4.patch, HIVE-6584.5.patch, HIVE-6584.6.patch, HIVE-6584.7.patch, > HIVE-6584.8.patch, HIVE-6584.9.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
