[jira] [Created] (YARN-11899) TestRouterMetrics is order dependent

Paco Chan created YARN-11899:
--------------------------------

             Summary: TestRouterMetrics is order dependent
                 Key: YARN-11899
                 URL: https://issues.apache.org/jira/browse/YARN-11899
             Project: Hadoop YARN
          Issue Type: Test
            Reporter: Paco Chan


The following tests are order-dependent if interleaved with other tests:
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testAppsFailedCreated|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testAppsFailedKilled|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testAppsFailedSubmitted|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testAppsReportFailed|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testMulipleAppsReportFailed|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testSucceededAppsCreated|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testSucceededAppsKilled|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testSucceededAppsReport|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testSucceededAppsSubmitted|
|org.apache.hadoop.yarn.server.router.TestRouterMetrics.testSucceededMultipleAppsReport|

 

This is because there is some state in the metrics that is not cleaned after the test is run. Some other tests can mutate the router metrics between tests.

 

To solve this problem, the metrics were reset after every test.
