```     
 try {
        doBatchOp(builder, region, quota, mutations, cellScanner, spaceQuotaEnforcement, false);
      } catch (IOException ioe) {
        rpcServer.getMetrics().exception(ioe);
        NameBytesPair pair = ResponseConverter.buildException(ioe);
        resultOrExceptionBuilder.setException(pair);
        context.incrementResponseExceptionSize(pair.getSerializedSize());
        builder.addResultOrException(resultOrExceptionBuilder.build());
      }
```
 #resultOrExceptionBuilder.setException(pair) here maybe need replace to #builder.setException(pair)?

> Support all mutations in BatchOperations to be applied atomically (all or none) by locking
all rows corresponding to mutations exclusively.
> mutateRows() which uses MultiRowMutationProcessor applies all mutations atomically and
batchMutate() is non-atomic. To unify code paths, isAtomic() attribute can be added to BatchOperations.
