[jira] [Created] (HDFS-15678) TestDFSOutputStream#testCloseTwice implementation is broken

Ahmed Hussein created HDFS-15678:
------------------------------------

             Summary: TestDFSOutputStream#testCloseTwice implementation is broken
                 Key: HDFS-15678
                 URL: https://issues.apache.org/jira/browse/HDFS-15678
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: dfs
            Reporter: Ahmed Hussein
            Assignee: Ahmed Hussein


[~daryn] noticed that the test {{TestDFSOutputStream#testCloseTwice}} was "cheating" by relying on incorrect behavior to pass. It closes a stream, injects an exception into the stream, closes and verifies injected exception is thrown, closes again and verifies no exception. The problem is a closed stream must never throw again so the injection should be a no-op.
