Bikas Saha commented on TEZ-1127:
---------------------------------
Per offline discussion, TEZ-699 will infer -xmx java opts based on task memory
size.
This jira will track adding a config for java opts and env. These may be used
to augment a job without re-compiling. The default value of the env config
could take care of adding LD_LIBRARY_PATH. This would serve as an example and
also prevent unnecessary addition of LD_LIBRARY_PATH inside the code. If its
not needed, the client config could be updated to remove it.
> Add TEZ_TASK_JAVA_OPTS and TEZ_ENV configs to specify values from config

> Key: TEZ-1127
> URL: https://issues.apache.org/jira/browse/TEZ-1127
> Project: Apache Tez
> Issue Type: Sub-task
> Affects Versions: 0.4.0
> Reporter: Pala M Muthaia
>
> There is no global setting available to specify JVM parameters for tez tasks
> (e.g: specifying native library location with java.library.path). Yarn allows
> specifying application.classpath, but not java opts. The only option right
> now is to set mapreduce.map.java.opts in the tez job config (or
> hive.tez.java.opts for Hive on Tez).
> Suggestion from Bikas, while discussing this in tez-user group, is tez should
> have "TEZ_TASK_JAVA_OPTS so that you don’t have to specify this via mapreduce
> configuration parameters"
