> In mapred-env, set HADOOP_JOB_HISTORYSERVER_HEAPSIZE 1000 by default, That is incorrect.
> We should set it 1000 by default only if it's empty. 
> Because if you run  'HADOOP_JOB_HISTORYSERVER_HEAPSIZE =512 $HADOOP_HOME/sbin/mr-jobhistory-daemon.sh
start historyserver', HADOOP_JOB_HISTORYSERVER_HEAPSIZE  will be set 1000, rather than 512.
