> JVM crash when displaying RPC params by MonitoredRPCHandler
> -----------------------------------------------------------
>
> Key: HBASE-26087
> URL: https://issues.apache.org/jira/browse/HBASE-26087
> Project: HBase
> Issue Type: Bug
> Components: UI
> Affects Versions: 3.0.0-alpha-1, 2.0.0
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Major
>
> It is the same problem as HBASE-25981.
> The reason here is MonitoredRPCHandlerImpl uses the shallow copy of call
> param to displaying RPC info, but the param contains offheap request data.
> Thought when calling toMap() there is state checking for the monitored RPC,
> only RUNNING RPCs can read and display params, the state is ENUM type and
> like a constant in clone().
> So there exists circumstances that the state in the clone MonitoredRPCHandler
> is RUNNING, but the param still refers to the cloned MonitoredRPCHandler,
> whose state changed to be not RUNNING and param referred offheap ByteBuffer
> is released.
