This jira is about a broken test case in branch-0.23 only.
HDFS-4233, testAllEditsDirsFailOnFlush started making subsequent cases in the same file fail. This is because MiniDFSCluster won't shutdown cleanly due to logSync() failure caused by lack of active journal streams. Without HDFS-4233, the condition was not detected and logSync() incorrectly ran without any error. To make MiniDFSCluster shutdown cleanly after a crash, the edit log needs to be aborted.
