Since it can lead to failing other tests. For example,= =C2=A0TestRMContainerAllocator#testReportedAppProgress fails when run after= TestMRAppMetrics#testNames with the following error: > {noformat} > org.apache.hadoop.metrics2.MetricsException: Metrics source MRAppMetrics = already exists! > {noformat} > !image-2018-09-10-14-39-57-992.png! > We do not catch this on the trunk since the test TestRMContainerAllocator= #testUnsupportedMapContainerRequirement run first and "DefaultMetricsSystem= .shutdown();" invokes after completion. But since JUnit does not guarantee = the order of the tests we should fix it.=C2=A0 > Also, this is affected by previous versions which run testReportedAppProg= ress first (I faced it on 2.7.0 version). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-help@hadoop.apache.org
