Ravi Prakash commented on HADOOP-13773:
---------------------------------------

Just for future reference. I've added you to the Contributors1 role. That would allow you
to assign issues to yourself. Also, please follow the patch naming scheme. All patch files
should have a version. Also, if the patch is not for trunk, it should contain the branch name.
So the file name for your patch should be HADOOP-13773.branch-2.01.patch. 

Thanks for your contribution and we look forward to many more from you!

> in conf/hadoop-env.sh,
> export HADOOP_CLIENT_OPTS="-Xmx512m $HADOOP_CLIENT_OPTS"
> when i set HADOOP_HEAPSIZE ,and run 'hadoop jar ...', jvm args is not work.
> i see, in bin/hadoop,
> exec "$JAVA" $JAVA_HEAP_MAX $HADOOP_OPTS $CLASS "$@"
> HADOOP_OPTS is behind JAVA_HEAP_MAX, so HADOOP_HEAPSIZE is not work.
> for example i run 'HADOOP_HEAPSIZE=1024 hadoop jar ...' , the java process is 'java -Xmx1024m
... -Xmx512m...', then Xmx512m is valid´╝î and Xmx1024m is invalid
