---------------------------------------
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.
