HDDS-1798. Propagate failure in writeStateMachineData to Ratis. Contributed by
Supratim Deka
URL: https://github.com/apache/hadoop/pull/1113
https://issues.apache.org/jira/browse/HDDS-1798
unit test is pending. Will add the infra required for testing this change as
part of https://issues.apache.org/jira/browse/HDDS-1818
writeStateMachineData() currently returns a future to Ratis. The scope of
this jira is to signal any errors or failures encountered as part of the
operation - WriteChunk / handleWriteChunk() to Ratis via this future. As of
now, the future does not track failures.
This change is required to complete the failure handling done in HDDS-1603.

> 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.
