Ayush Saxena commented on HDFS-17017:
-------------------------------------
Is that an intersection of the arguments? It goes to all arguments and print
each category of nodes requested. slow and dead means it will print slow nodes
and the dead nodes.
If it was intersection -live and -dead will always be 0
> Fix the issue of arguments number limit in report command in DFSAdmin.
