Kihwal Lee commented on MAPREDUCE-3259:
---------------------------------------
- The test failure is not related to the patch. It fails because the test hard
codes the user name.
junit.framework.ComparisonFailure: Incorrect username expected:<[mapred]> but
was:<[jenkins]>
- None of the findbugs warnings are related to this patch or new.
- Testing require deployment with a set of specific configurations. As reported
above, it was done manually.

> Key: MAPREDUCE-3259
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3259
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: mrv2, nodemanager
> Affects Versions: 0.23.0, 0.24.0
> Reporter: Kihwal Lee
> Assignee: Kihwal Lee
> Priority: Blocker
> Fix For: 0.23.0, 0.24.0

> As seen in MAPREDUCE-2915, java.library.path is not being passed when the LCE
> spawns a JVM for ContainerLocalizer.
> However, unlike branch-0.20-security, the task runtime in 0.23 is unaffected
> by this. This is because tasks' run-time environment is specified in the
> launch script by client. Setting LD_LIBRARY_PATH is the primary way of
> specifying the locations of required native library in this case. The config
> property, mapreduce.admin.user.env is always set in the job environment and
> the default value is to add the path to the hadoop native library to
> LD_LABRARY_PATH.
> For JVM's being launched by the hadoop system scripts, java.library.path is
> set.
