Subject [jira] Commented: (HBASE-2817) Allow separate HBASE_REGIONSERVER_HEAPSIZE and HBASE_MASTER_HEAPSIZE
Date Wed, 07 Jul 2010 00:11:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2817?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12885749#action_12885749
] 

Jean-Daniel Cryans commented on HBASE-2817:
-------------------------------------------

In hbase-env.sh we have this which looks like what Hadoop has:

{code}

# export HBASE_JMX_BASE="-Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"
# export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS $HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10101"
# export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS $HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10102"
# export HBASE_THRIFT_OPTS="$HBASE_THRIFT_OPTS $HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10103"
# export HBASE_ZOOKEEPER_OPTS="$HBASE_ZOOKEEPER_OPTS $HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10104"

{code}

The -Xmx's kinda already easy to add this way.  You want to break it out even more?

> Right now we have a single HBASE_HEAPSIZE configuration. This isn't that great, since
the HMaster doesn't really need much ram compared to the region servers. We should allow different
java options and heapsize for the different daemon types.
> Probably worth breaking out THRIFT, REST, AVRO, etc, as well.
