Subject Re: How to set JVM arguments in Hadoop 0.23
Date Wed, 12 Sep 2012 03:46:51 GMT
Hi Shekhar,

For YARN, try setting YARN_OPTS inside the yarn-env.sh. YARN scripts
do not reuse the hadoop-env.sh like the rest of the components. The
yarn-env.sh must reside in the YARN_CONF_DIR directory.

Does this help?
