    • Release Note:
      New environment variables were introduced to allow finer grained control of Java options passed to server and client JVMs. See the new *_OPTS variables in conf/hadoop-env.sh.

      Description

      We often configure our HADOOP_OPTS on the name node to have JMX running so that we can do JVM monitoring. But doing so means that we need to edit this file if we want to run other hadoop commands, such as fsck. It would be useful if hadoop-env.sh was refactored a bit so that there were different and/or cascading HADOOP_OPTS dependent upon which process/task was being performed.
