--------------------------------------------

             Summary: ConnectionQueryServicesImpl.createSnapshot bounded retry on transient exception
                 Key: PHOENIX-7820
                 URL: https://issues.apache.org/jira/browse/PHOENIX-7820
             Project: Phoenix
          Issue Type: Sub-task
          Components: core
            Reporter: Andrew Kyle Purtell
            Assignee: Andrew Kyle Purtell
             Fix For: 5.4.0, 5.3.1


{{ConnectionQueryServicesImpl.createSnapshot()}} invokes {{admin.snapshot()}} during the Phoenix upgrade path. Transient HMaster issues surface as upgrade failures because of the lack of retry. The master's per-table lock can be briefly held by a concurrent admin operation, or RPC-level retries can resubmit an already-accepted snapshot request, causing the master to reject the duplicate. The fix is to wrap the snapshot call in a small bounded retry loop (5 attempts, 1 s backoff).
