Lars Hofhansl commented on HBASE-7658:
--------------------------------------
Looks good. Anybody concerned with backward compatibility issues? (somebody
could have used empty perms before, now they'll get an exception). Just
mentioning this. +1 from me, including 0.94.
> grant with an empty string as permission should throw an exception
