> 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}
