[jira] [Created] (HDFS-6062) TestRetryCacheWithHA#testConcat is flaky

Jing Zhao created HDFS-6062:
-------------------------------

             Summary: TestRetryCacheWithHA#testConcat is flaky
                 Key: HDFS-6062
                 URL: https://issues.apache.org/jira/browse/HDFS-6062
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Jing Zhao
            Assignee: Jing Zhao
            Priority: Minor
         Attachments: HDFS-6062.000.patch

After adding retry cache metrics check, TestRetryCacheWithHA#testConcat can fail (https://builds.apache.org/job/PreCommit-HDFS-Build/6313//testReport/).

The reason is that the test uses "dfs.exists(targetPath)" to check whether concat has been done in the original active NN. However, since we create the target file in the beginning, the check always returns true. Thus it is possible that the concat is processed in the new active NN for the first time. And in this case the retry cache will not be hit.
