Subject [jira] [Commented] (YARN-1329) yarn-config.sh overwrites YARN_CONF_DIR indiscriminately

Roman Shaposhnik commented on YARN-1329:
----------------------------------------

> The script yarn-daemons.sh calls {code}${HADOOP_LIBEXEC_DIR}/yarn-config.sh{code}
> yarn-config.sh overwrites any previously set value of environment variable YARN_CONF_DIR

> #check to see if the conf dir is given as an optional argument
