Subject [jira] [Updated] (MAPREDUCE-5514) TestRMContainerAllocator fails on trunk
Date Fri, 20 Sep 2013 18:09:53 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-5514?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Zhijie Shen updated MAPREDUCE-5514:

    Attachment: MAPREDUCE-5514.1.patch

I checked the test code. TestRMContainerAllocator fails at testReportedAppProgress and testReportedAppProgressWithOnlyMaps,
because job.xml cannot be found when constructing containerLaunchContext.

Looked into the detail. job.xml was actually created, but path is wrong. It was created at:


but was expected to read from:

{code} /Users/zshen/Documents/Workspace/eclipse/hadoop-2/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-app/target/org.apache.hadoop.mapreduce.v2.app.TestRMContainerAllocator/appattempt_1379525411704_0001_000001/.staging/job_1379525411704_0001/job.xml


Note that there's a section of attempt id in both paths. This section is the user name from
UserGroupInformation.getCurrentUser().getShortUserName() (refer to how the path is created
in TaskAttemptImpl). The user name was set to  the attempt id, and it differs for each TaskAttempt.
Therefore, the path to job.xml is wrong for the other tasks.

See the following code:
    protected void register() {
      ApplicationAttemptId attemptId = getContext().getApplicationAttemptId();
      UserGroupInformation ugi =
      Token<AMRMTokenIdentifier> token =
      try {
      } catch (IOException e) {
        throw new YarnRuntimeException(e);

We just need to use an identical user name instead of attemptId for UGI.
