>             Project: Apache Tez
>          Issue Type: Bug
>    Affects Versions: 0.5.0
>            Reporter: Subroto Sanyal

>             Fix For: 0.5.0

> As part of the fix for the issue TEZ-1127 two new configurations have  been introduced:
> # _TEZ_AM_LAUNCH_ENV_
> # _TEZ_TASK_LAUNCH_
> Ideally these properties should be configured with default value of:
> "LD_LIBRARY_PATH=$HADOOP_COMMON_HOME/lib/native"
> as in the case for _mapreduce.admin.user.env_
> The default value for these properties are set to "" (empty string).
> Now user has to explicitly set these values from the application code to use the native libs (like for compression).
> From Hitesh:
> {quote}As commented on TEZ-1127, it is a question as to what the default should be - whether HADOOP_COMMON_HOME or HADOOP_PREFIX and to some extent, it needs to handle Windows deployments too.{quote}
