> Currently,
> writeStateMachineData() returns a future to Ratis. This future does not track
> any errors or failures encountered as part of the operation - WriteChunk /
> handleWriteChunk(). The error is propagated back to the client in the form of
> an error code embedded inside writeChunkResponseProto. But the error goes
> undetected and unhandled in the Ratis server. The future handed back to Ratis
> is always completed with success.
> The goal is to detect any errors in writeStateMachineData in Ratis and treat
> is as a failure of the Ratis log. Handling for which is already implemented
> in HDDS-1603.
