Edward Capriolo updated HIVE-3603: ---------------------------------- Resolution: Fixed Status: Resolved (was: Patch Available) Thanks Navis. > Enable client-side caching for scans on HBase > --------------------------------------------- > > Key: HIVE-3603 > URL: https://issues.apache.org/jira/browse/HIVE-3603 > Project: Hive > Issue Type: Improvement > Components: HBase Handler > Reporter: Karthik Ranganathan > Assignee: Navis > Priority: Minor > Fix For: 0.12.0 > > Attachments: HIVE-3603.D7761.1.patch > > > HBaseHandler sets up a TableInputFormat MR job against HBase to read data in. > The underlying implementation (in HBaseHandler.java) makes an RPC call per > row-key, which makes it very inefficient. Need to specify a client side cache > size on the scan. > Note that HBase currently only supports num-rows based caching (no way to > specify a memory limit). Created HBASE-6770 to address this. -- This message is automatically generated by JIRA.
