`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). -- This is an automated message from the Apache Git Service.
