[jira] [Created] (HBASE-20107) Add a test case for HBASE-14317

Zephyr Guo created HBASE-20107:
----------------------------------

             Summary: Add a test case for HBASE-14317
                 Key: HBASE-20107
                 URL: https://issues.apache.org/jira/browse/HBASE-20107
             Project: HBase
          Issue Type: Improvement
          Components: wal
    Affects Versions: 3.0.0
            Reporter: Zephyr Guo
             Fix For: 3.0.0


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` get out stuck.

 Here, we add a new test case to simulate stuck RS correctly.
