Ashish Singhi commented on HBASE-13755:
---------------------------------------

I mentioned that point to avoid remarks of this [kind | 
http://blog.tsunanet.net/2012/04/apache-hadoop-abuse-ioexception.html].
bq. In initialize() method, we have User.getCurrent() call inside, which throws 
IOException anyway.. not sure it'd good idea to catch it and re-translate to 
something else
Lets not catch any exception thrown from an existing method and re-translate it 
to something else but instead lets not throw IOE by ourselves when user is null.

> Provide single super user check implementation
