Siddharth Seth resolved YARN-449.
---------------------------------
Resolution: Fixed
Fix Version/s: 2.0.4-alpha
Summarizing for reference, and closing this since HBASE-7904 is committed.
Critical fixes to YARN
YARN-429 fixes capacity-scheduler.conf being unavailable.
Additional fixes which (in most cases) don't affet HBASE, but could affect
other projects using the MiniMRCluster
YARN-470 and MAPREDUCE-5094 (wip) - disable memory monitoring by default in
the MiniMRYARNCluster
MAPREDUCE-5083 - Randomize MiniMRCluster directory component, to allow
parallel instances
Changes to HBase (HBASE-7904)
Fixes to TestImportExport to copy yarn configuration in all cases.
Changes to HBaseTestingUtility to merge the configuration returned by
MiniMRCluster.
Chane to HRegion to not use a 'CompoundConfiguration' when talking to HDFS,
due to the inability to change the RPC engine with CompoundConfiguration.
(Causes several *SecureLoad tests to hang)
> HBase test failures when running against Hadoop 2

> Key: YARN-449

> Project: Hadoop YARN
> Issue Type: Bug
> Affects Versions: 2.0.3-alpha
> Reporter: Siddharth Seth
> Priority: Blocker
> Fix For: 2.0.4-alpha
>
> Attachments: 7904-v5.txt, hbase-7904-v3.txt,

>
>
> Post YARN-429, unit tests for HBase continue to fail since the classpath for
> the MRAppMaster is not being set correctly.
> Reverting YARN-129 may fix this, but I'm not sure that's the correct
> solution. My guess is, as Alexandro pointed out in YARN-129, maven
> classloader magic is messing up java.class.path.
