[jira] [Created] (HDFS-12967) NNBench should support multi-cluster access

Chen Zhang created HDFS-12967:
---------------------------------

             Summary: NNBench should support multi-cluster access
                 Key: HDFS-12967
                 URL: https://issues.apache.org/jira/browse/HDFS-12967
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: benchmarks
            Reporter: Chen Zhang


Sometimes we need to run NNBench for some scaling tests after made some improvements on NameNode, so we have to deploy a new HDFS cluster and a new Yarn cluster.
If NNBench support multi-cluster access, we only need to deploy a new HDFS test cluster and add it to existing YARN cluster, it'll make the scaling test easier.

Even more, if we want to make some A-B test, we have to run NNBench on different HDFS clusters, this patch will be helpful.
