Looped 10 times and all passed. To me your original failure was caused by the CountDownLatch not be protected by a final statement, which was fixed in HDFS-6231(it's available since 2.4.1) by [~cnauroth]. I'd like to close the current jira due to duplicated. [~liulei.cn], if you still can repro it after 2.4.1, please feel free to reopen it, thanks all the same!
