[jira] [Commented] (MAPREDUCE-4966) Env variable for JobHistory JVM OPTS

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4966?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13564850#comment-13564850 ] 

Thomas Graves commented on MAPREDUCE-4966:
------------------------------------------

this already exists - HADOOP_JOB_HISTORYSERVER_OPTS. There is also HADOOP_JOB_HISTORYSERVER_HEAPSIZE.

see http://svn.apache.org/viewvc/hadoop/common/trunk/hadoop-mapreduce-project/conf/mapred-env.sh?revision=1390224&view=markup

> There seems to be no option to set JVM OPTS for JobHistoryServer. One of the common setting is having Xmx value passed to it. As of now it can be done only via JVM_OPTS or HADOOP_CLIENT_OPTS. It would be good to have something specific for JobHistoryServer
