             Summary: During HBase 2 upgrade Phoenix Self healing task fails to create server side connection before reading SYSTEM.TASK
                 Key: PHOENIX-6758
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6758
             Project: Phoenix
          Issue Type: Bug
            Reporter: Viraj Jasani
            Assignee: Viraj Jasani
             Fix For: 5.2.0, 5.1.3


When HBase master is running on 1.x version and regionservers are on 2.x version (specifically system rsgroup regionservers), TaskRegionObserver fails to initiate connection to read SYSTEM.TASK records. While this task itself is not a customer facing usecase, but we should fix the task being unable to initiate connection for the first time. Once the connection is created, it is anyways cached in CQSI.

We should support fallback for admin#tableExists for Phoenix server side dealing of CQSI#init.
