             Summary: Fix Intermittent failure on TestProcedurePriority
                 Key: HBASE-20907
                 URL: https://issues.apache.org/jira/browse/HBASE-20907
             Project: HBase
          Issue Type: Test
            Reporter: Yu Li
            Assignee: Yu Li


From a local UT check against 2.1.0-RC1, HMaster failed to initialize before time out. Checking the test log we could see below message:

In current test code we will set {{FAIL}} to true w/o checking whether namespace manager is already up, and if not lucky we will run into the above case and get a timeout.

The fix will be quite straight forward.
