Subject Re: Questions on Namespace/namenode

NameNode is a HDFS bottleneck, so running multiple namespaces within 
only one NN is a risky. What do you want to achieve?

It might help you a bit - HDFS Federation 
<https://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-hdfs/Federation.html>.
