> Support for Namenode HA for non-idempotent operations
> -----------------------------------------------------
>
> Key: HBASE-8156
> URL: https://issues.apache.org/jira/browse/HBASE-8156
> Project: HBase
> Issue Type: Sub-task
> Components: Filesystem Integration
> Affects Versions: 0.95.0
> Reporter: Himanshu Vashishtha
> Assignee: Himanshu Vashishtha
> Fix For: 0.98.0
>
> Attachments: HBase-8156-trunk-v1.patch
>
>
> 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.
