Subject: [jira] [Updated] (HBASE-12607) TestHBaseFsck#testParallelHbck fails

Ted Yu updated HBASE-12607:
---------------------------
    Issue Type: Bug  (was: Test)

The current code depends on a bug in hdfs which was fixed in hadoop 2.6.0

With the bug fixed, the second attempt at invoking hbck would keep on retrying until it can successfully create the lock file.

Proposed fix is to fail the second attempt since initiation of the second attempt overlaps the first invocation of hbck.
