--------------------------------------------
Summary: NPE in Phoenix Coproc leading to Region Server crash
Key: PHOENIX-7245
URL: https://issues.apache.org/jira/browse/PHOENIX-7245
Project: Phoenix
Issue Type: Bug
Components: phoenix
Affects Versions: 5.1.1

In our Production, while investigating Region Server crashes, we found that it
is due to Phoenix coproc throwing Null Pointer Exception in
IndexRegionObserver.postBatchMutateIndispensably() method.
Below are the logs
