Ivan A. Veselovsky commented on MAPREDUCE-4764:
-----------------------------------------------

The failed test org.apache.hadoop.mapred.TestClusterMRNotification.testMR appears to be flaky: it fails in many previous pre-commit builds.
Re-submitting the patch to try again.
                
> repair test org.apache.hadoop.mapreduce.security.TestBinaryTokenFile

> the test is @Ignore-ed, and fails being enabled.
> Suggested to repair it to fill the coverage gap.
> Problems fixed in the test: 
> (1) MRConfig.FRAMEWORK_NAME and YarnConfiguration.RM_PRINCIPAL properties must be correctly set in the configuration to correctly enable the security in the way this test implies. 
> (2) The property MRJobConfig.MAPREDUCE_JOB_CREDENTIALS_BINARY now is not passed into the Job configuration -- it is intentionally deleted from there. So, we pass the binary file name in another dedicated property. 
> (3) The test was using deprecated cluster classes. All them are updated to the modern analogs.
> (4) The delegation token found in the job context is now correctly compared to the one deserialized from the binary file.
