Subject [jira] [Created] (HBASE-8036) ProtobufUtil.multi behavior is incosnsistent in case of errors

Sergey Shelukhin created HBASE-8036:
---------------------------------------

             Summary: ProtobufUtil.multi behavior is incosnsistent 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.
