> Project: Hadoop Map/Reduce
> Issue Type: Bug

> Affects Versions: 0.20.205.0

>
> When a job is submitted, LinuxTaskController launches the native
> task-controller binary for job initialization. The native program does a
> series of prep work and call execv() to run JobLocalizer. It was observed
> that JobLocalizer does fails to run when JniBasedUnixGroupsNetgroupMapping or
> JniBasedUnixGroupsMapping is enabled, resulting in 100% job failures.
> JobLocalizer normally does not need the native library (libhadoop) for its
> functioning, but enabling a JNI user-to-group mapping function cause it to
> load the library. However, JobLocalizer cannot locate the library since
> "java.library.path" is not set.
> The proposed solution is to pass the java.library.path property through
> task-controller. LinuxTaskController already does it when launching the task
> log truncater.
