Subject [jira] [Commented] (YARN-449) MRAppMaster classpath not set properly for unit tests in downstream projects
Date Tue, 12 Mar 2013 16:49:15 GMT

    [ https://issues.apache.org/jira/browse/YARN-449?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600169#comment-13600169
] 

Ted Yu commented on YARN-449:
-----------------------------

On flubber, I installed protoc 2.4.1 but couldn't use it:
{code}
$ protoc --version
protoc: error while loading shared libraries: libprotobuf.so.7: cannot open shared object
file: No such file or directory
{code}
I applied minimr_randomdir-branch2.txt locally and ran the following command:

mt -Dhadoop.profile=2.0 -Dtest=org.apache.hadoop.hbase.mapreduce.TestTableMapReduce#testMultiRegionTable

The test passed.

> 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.
