[jira] [Created] (PHOENIX-3535) Fix race condition in ConnectionQueryServicesImpl#acquireUpgradeMutex

Samarth Jain created PHOENIX-3535:
-------------------------------------

             Summary: Fix race condition in ConnectionQueryServicesImpl#acquireUpgradeMutex
                 Key: PHOENIX-3535
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3535
             Project: Phoenix
          Issue Type: Bug
            Reporter: Samarth Jain


Conversation on HBASE-17300 revealed that concurrently creating a table, checking for its existence and performing an operation on it is fraught with races. This race condition is causing UpgradeIT#testConcurrentUpgradeThrowsUpgradeInProgressException to fail. We need to figure out a way for not creating/checking existence of the SYSTEM.MUTEX table.
