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}
> Tez job gets "Could not load native gpl library or native-lzo library" error

> 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.
