----------------------------------
Summary: JVM crash when displaying regionserver UI
Key: HBASE-25981
URL: https://issues.apache.org/jira/browse/HBASE-25981
Project: HBase
Issue Type: Bug
Components: rpc, UI
Affects Versions: 2.0.0, 3.0.0-alpha-1
Reporter: Xiaolin Ha
Assignee: Xiaolin Ha
Attachments: hs_err_pid116190.log-gha-data-hbase-cat0085-ui
The MonitoredRPCHandlerImpl refers to the params of a request, and will show
them when we call 'toJson()'. But the running RPC call may be cleaned up and
the ByteBuffer be released before the displaying in UI. We need to let the
life cycle of RPC status monitor be inner the life cycle of RPC.
