Example 10 with RegionAction

use of org.apache.hadoop.hbase.shaded.protobuf.generated.ClientProtos.RegionAction in project hbase by apache.

the class MockMasterServices method buildMultiResponse.

private static MultiResponse buildMultiResponse(MultiRequest req) {

    ResultOrException.Builder roeBuilder = ResultOrException.newBuilder();
