> Key: TEZ-1418
> URL: https://issues.apache.org/jira/browse/TEZ-1418
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.5.0
> Reporter: Subroto Sanyal
> Priority: Blocker
> Fix For: 0.5.0

> Attachments: TEZ-1418.1.patch, TEZ-1418.patch

> 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}
