Arpit Agarwal updated HDDS-1798:
--------------------------------
Description:
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.
