-----------------------------------------
Summary: Remove duplicate calls to
getSysMutexPhysicalTableNameBytes() during the upgrade path
Key: PHOENIX-6085
URL: https://issues.apache.org/jira/browse/PHOENIX-6085
Project: Phoenix
Issue Type: Improvement
Affects Versions: 4.15.0, 5.0.0
Reporter: Chinmay Kulkarni
Fix For: 5.1.0, 4.16.0
We already make this call inside
[CQSI.acquireUpgradeMutex()|https://github.com/apache/phoenix/blob/1922895dfe5960dc025709b04acfaf974d3959dc/phoenix-core/src/main/java/org/apache/phoenix/query/ConnectionQueryServicesImpl.java#L4220]
and then call writeMutexCell() which calls this again
[here|https://github.com/apache/phoenix/blob/1922895dfe5960dc025709b04acfaf974d3959dc/phoenix-core/src/main/java/org/apache/phoenix/query/ConnectionQueryServicesImpl.java#L4244].
We should move this to inside writeMutexCell() itself and throw
UpgradeInProgressException if required there to avoid unnecessary expensive
HBase admin API calls.
