Description

Even after YARN-5362 the test is still flaky:

Tests run: 29, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 100.652 sec <<< FAILURE! - in org.apache.hadoop.yarn.server.resourcemanager.TestRMRestart

The test finishes with two asserts. This is the second assert that fails, YARN-5362 looked at a failure on the first of the two asserts
