Mithun Radhakrishnan commented on TEZ-1085:
-------------------------------------------

FWIW, +1. Good thing you moved the Pattern.compile() out to a static variable.

Minor typo in comment:
{code} // If the env key is note present leave {code}

> Even when mapreduce.admin.user.env property is set to LD_LIBRARY_PATH=$HADOOP_COMMON_HOME/lib/native and MRHelpers.updateEnvironmentForMRTasks(conf, taskEnv, isMap); is called it does not work if HADOOP_COMMON_HOME is not set on the client. TezYARNUtils.setEnvFromInputString sets an env variable to "" if not found. But HADOOP_COMMON_HOME will be set by the ContainerLaunch.java in YARN as part of YarnConfiguration.DEFAULT_NM_ENV_WHITELIST. So it is not necessary that the clients have HADOOP_COMMON_HOME set.
