Improve the efficiency of our MR jobs with a few configurations ---------------------------------------------------------------
Key: HBASE-4657 URL: https://issues.apache.org/jira/browse/HBASE-4657 Project: HBase Issue Type: Improvement Affects Versions: 0.90.4 Reporter: Jean-Daniel Cryans Fix For: 0.92.0 This is a low hanging fruit, some of our MR jobs like RowCounter and CopyTable don't even setCacheBlocks on the scan object which out of the box completely screws up a running system. Another thing would be to disable speculative execution. -- This message is automatically generated by JIRA.
