> In hadoop 2 HA, non-idempotent operations are not retried at the hdfs side.
> This is by design as retrying a non-idempotent operation might not be a good
> design choice for some use case.
> HBase needs to handle the retries for such operations at its end.
> With HBase-7806, there is already some work going on for file system
> abstractions. There, HReginFileSystem sits as an abstraction between region
> and FS. This jira is a move in the same direction, where it adds retry
> functionality for non-idempotent calls such as create, rename and delete in
> HRegionFileSystem class.
