-----------------------------------------------
Summary: TestTaskAttemptContainerRequest should reset
UserGroupInformation
Key: MAPREDUCE-7135
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7135
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: test
Reporter: Oleksandr Shevchenko
TestTaskAttemptContainerRequest should reset UserGroupInformation after end
since this test cache UserGroupInformation and can be cause of other test fail.
For example, all test in TestRMContainerAllocator will be failed if we run
these tests after TestTaskAttemptContainerRequest (or we can change
"UserGroupInformation.setLoginUser(null)" with UserGroupInformation.reset() in
this class).
Also, I think the WARNING message in TestTaskAttemptContainerRequest can be
removed since we can reset UserGroupInformation after each test.
