Tanping Wang commented on HADOOP-6977:
--------------------------------------
In the newer patch, "HADOOP_OPTS" is passed in as parameter to check
isJmxEnabled and getJmxPort. I assume if user uses specific options for each
demon, for example enabling JMX for name node daemon by passing in
HADOOP_NAMENODE_OPTS,
export HADOOP_NAMENODE_OPTS="-Dcom.sun.management.jmxremote
$HADOOP_NAMENODE_OPTS -Dcom.sun.management.jmxremote.port=8004″
then the parameter to be searched will be changed from "HADOOP_OPTS" to
"HADOOP_NAMENODE_OPTS". If my understanding is corret, I think the patch is
good.
