----------------------------------------------
[~aw] Thanks for taking a look into this issue..

I don't think HADOOP_JAVA_PLATFORM_OPTS is actually supported by any code
anymore.

Yes, you are correct..
And I can give like GC..
when I looked into GC SETTINGS, got following doubts
1) why it's mentioned only in NAMENODE_OPTS?
2) it should be nn.log right..? not rm.log..?
{code}
export HADOOP_NAMENODE_OPTS="${HADOOP_GC_SETTINGS}
-Xloggc:${HADOOP_LOG_DIR}/gc-rm.log-$(date +'%Y%m%d%H%M')"
{code}
> Add comment/docs to enable assertions in hadoop-env.sh

> For testing it's useful to enable jvm assertions. Let's add a commented out
> line to hadoop-env.sh that sets the "-enableassertions" and
> "-enablesystemassertions" jvm options to make it easier to run "debug"
> builds. Per HADOOP-8033 perhaps this should be HADOOP_JAVA_PLATFORM_OPTS.
