Aditya Kishore commented on HBASE-9756:
---------------------------------------
+1. Make sense, some time the real error message gets lost in the usage deluge.
Patch looks good.
> HBase shell help info would be better to display only when usage error
> instead of any exception

> When error occurred in HBase shell, no matter what error it is, the help info
> will display. As help info is used to instruct how to use the command, so it
> would be better to show help info only when the command is used in a wrong
> way.
