> ProtobufUtil.multi behavior is inconsistent in case of errors
> -------------------------------------------------------------
>
> Key: HBASE-8036
> URL: https://issues.apache.org/jira/browse/HBASE-8036
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.95.0
> Reporter: Sergey Shelukhin
> Fix For: 0.95.0
>
>
> ProtobufUtil splits operations by regions and performs multiple client.multi
> calls. In case if there are certain errors inside RS, HRegionServer adds the
> corresponding exceptions to MultiResponse, and PU continues the batch and
> returns partial failure.
> In case of other errors (for example, region not served exception), the
> entire batch stops executing, and previous successes and partial results are
> disregarded.
> ProtobufUtil should probably catch ServiceException separately for
> multi-region batches, and make it a partial result for all actions for this
> region (and also continue the batch), to make the behavior consistent.
> Alternatively server should do that for region-specific errors (add exception
> to results for each action), if we want to avoid continuing the batch in case
> of some server-wide errors/connection problems/etc.
