> RS might get stuck because of HBASE-14317. I met same problem in my hbase,
> and HBASE-14317 can solve this problmen very well.
> But I don't get stuck when I run
> _TestWalLockup.testLockupWhenSyncInMiddleOfZigZagSetup_.
> We'll never see stuck in this test case, because
> FailedSyncBeforeLogCloseException will break
> _zigzagLatch.waitSafePoint(SyncFuture)_. Finally,
> _zigzagLatch.releaseSafePoint()_ will be call, and _attainSafePoint(long)_
> get out stuck.
> Here, we add a new test case to simulate stuck RS correctly.
