Not sure why the Vmem is going that high. The hadoop-1 default config likely disables this monitoring. At this point there seem to be solutions for the original prolem the jira was opened for, and this is really re-purposed to get HBase unit tests working with Hadoop 2. Changing the title accordingly. > MRAppMaster classpath not set properly for unit tests in downstream projects > ---------------------------------------------------------------------------- > > Key: YARN-449 > URL: https://issues.apache.org/jira/browse/YARN-449 > Project: Hadoop YARN > Issue Type: Bug > Affects Versions: 2.0.3-alpha > Reporter: Siddharth Seth > Priority: Blocker > Attachments: 7904-v5.txt, hbase-7904-v3.txt, > hbase-TestHFileOutputFormat-wip.txt, hbase-TestingUtility-wip.txt, > minimr_randomdir-branch2.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. -- This message is automatically generated by JIRA.
