Subject [jira] [Commented] (YARN-449) MRAppMaster classpath not set properly for unit tests in downstream projects
Date Tue, 05 Mar 2013 01:38:11 GMT

    [ https://issues.apache.org/jira/browse/YARN-449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13592915#comment-13592915

Hitesh Shah commented on YARN-449:

This probably will work for a short term until the internal implementation of MiniYarnCluster
or any other minicluster for that matter introduces a new config property that it needs/refers

Looking at the hbase tests, it seems like that instead of using the config object returned
by the MiniMRCluster and building on top of it, it tries to do some form of a union between
2 confs. In such cases, chances of missing some internal settings are always likely. I believe
there was an earlier fix to set the framework.name to 'yarn' to solve something similar to
the current problem when hbase starting running tests against 0.23.

[~tedyu@apache.org], do you have any comments on the above? Is it possible to change the base
test class for hbase unit tests to build upon the config provided by the mini cluster? Any
reason for not doing so?

>             Project: Hadoop YARN
>          Issue Type: Bug
>    Affects Versions: 2.0.3-alpha
>            Reporter: Siddharth Seth
>            Priority: Blocker
>         Attachments: hbase-TestHFileOutputFormat-wip.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.
