Subroto Sanyal created TEZ-1418:
-----------------------------------
Summary: Default value for TEZ_AM_LAUNCH_ENV and TEZ_TASK_LAUNCH
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
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}
