> Project: HBase

> Components: hbck, test
> Affects Versions: 2.0.0, 1.1.0, 1.2.0
> Reporter: Stephen Yuan Jiang

> Running TestHBaseFsck#testParallelHbck is flaky against HADOOP-2.6+
> environment. The idea of the test is that with when 2 HBCK operations are
> running simultaneously, the 2nd HBCK would fail with no-retry because
> creating lock file would fail due to the 1st HBCK already created. However,
> with HADOOP-2.6+, the FileSystem#createFile call internally retries with
> AlreadyBeingCreatedException (see HBASE-13574 for more details: "It seems
> that test is broken due of the new create retry policy in hadoop 2.6.
> Namenode proxy now created with custom RetryPolicy for
> AlreadyBeingCreatedException which is implies timeout on this operations up
> to HdfsConstants.LEASE_SOFTLIMIT_PERIOD (60seconds).")
> When I run the TestHBaseFsck#testParallelHbck test against HADOOP-2.7 in a
> Windows environment (HBASE is branch-1.1) multiple times, the result is
> unpredictable (sometime succeeded, sometime failed - more failure than
> succeeded).
> The fix is trivial: Leverage the change in HBASE-13732 and reduce the max
> wait time to a smaller number.
