------------------------------------------
Summary: Configs: HBase heap sizes should not be set to 1GB
Key: AMBARI-8989
URL: https://issues.apache.org/jira/browse/AMBARI-8989
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: 2.0.0
Reporter: Dmitry Lysnichenko
Assignee: Dmitry Lysnichenko
Fix For: 2.0.0
Ambari installs are still hard coding heap sizes to 1GB. We have seen many
tickets filed whose resolution was to increase regionserver sizes to 4GB. I
think these should be adjusted.
Here is what I got from the Ambari install:
{code}
export HBASE_OPTS="$HBASE_OPTS -XX:+UseConcMarkSweepGC
-XX:ErrorFile=/var/log/hbase/hs_err_pid%p.log"
export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -Xmx1024m"
export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -Xmn200m
-XX:CMSInitiatingOccupancyFraction=70 -Xms1024m -Xmx1024m"
{code}
