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