[jira] [Created] (MAPREDUCE-7137) MRAppBenchmark.benchmark1() fails with NullPointerException

Oleksandr Shevchenko created MAPREDUCE-7137:
-----------------------------------------------

             Summary: MRAppBenchmark.benchmark1() fails with NullPointerException
                 Key: MAPREDUCE-7137
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-7137
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: test
            Reporter: Oleksandr Shevchenko


MRAppBenchmark.benchmark1() fails with NullPointerException:
1. We do not set any queue for this test. As the result we got the following exception:
{noformat}

{noformat}
2. We override createSchedulerProxy method and do not set application priority that was added later by MAPREDUCE-6515. We got the following error:
{noformat}
java.lang.NullPointerException
 at org.apache.hadoop.mapreduce.v2.app.rm.RMContainerAllocator.handleJobPriorityChange(RMContainerAllocator.java:1025)

 at java.lang.Thread.run(Thread.java:748)
{noformat}
In both cases, the job never will be run and the test stuck and will not be finished.
