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.
