Mapping a very big table kills region servers
---------------------------------------------
Key: HBASE-2252
URL: https://issues.apache.org/jira/browse/HBASE-2252
Project: Hadoop HBase
Issue Type: Bug
Reporter: Jean-Daniel Cryans
Fix For: 0.20.4, 0.21.0
Currently TableInputFormat doesn't change the block caching behavior of scans
and one of our table grew so big that using the defaults we kill a least one
region server per job run (because of GCs even if we have a heap of 7GB). This
doesn't scale well, we should set it by default to false.
