Brahma Reddy Battula commented on HDFS-13867:
---------------------------------------------
Instead of throwing the IAE,how about giving command usage itself..? i. e.
printUsage(cmd);
If you all agree, this can be done along with HDFS-13861..?

> Add validation to check if the total number of arguments provided for the
> Router Admin commands are not more than max possible.In most cases if there
> are some non related extra parameters after the required arguments it doesn't
> validate against this but instead perform the action with the required
> parameters and ignore the extra ones which shouldn't be in the ideal case.
