Description

Running the below sequence of steps should give a better error messaging rather than "table not found" error.

hbase(main):009:0> grant "test", "RWCXA"

ERROR: Unknown table _acl_!

Here is some help for this command:
Grant users specific rights.
Syntax : grant <user> <permissions> [<table> [<column family> [<column qualifier>]]

permissions is either zero or more letters from the set "RWXCA".
READ('R'), WRITE('W'), EXEC('X'), CREATE('C'), ADMIN('A')

For example:

    hbase> grant 'bobsmith', 'RWXCA'
    hbase> grant 'bobsmith', 'RW', 't1', 'f1', 'col1'

Instead of ERROR: Unknown table acl!, hbase should give out a warning like "Command not supported in non-authz mode(as acl table is only created if authz is turned on)"
