> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: benchmarks
> Reporter: Chen Zhang
> Assignee: 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 do some A-B test, we have to run NNBench on
> different HDFS clusters, this patch will be helpful.
