Brandon Williams commented on CASSANDRA-4177:
---------------------------------------------

This patch isn't really going to solve anything for you, except remove the "Could not retrieve endpoint ranges" prefix, which is still technically correct.

> After adding BulkRecordWriter (or actually ExternalClient) the ability to make use of authentication I've noticed that exceptions that are thrown on login failure are very misguiding - there's always a "Could not retrieve endpoint ranges" RuntimeException being thrown, no matter what really happens. This "hides" the real reason of all authentication problems. I've changed this line a bit, so all the messages are passed without any change, so now I get - for example - "AuthenticationException(why:Given password in password mode MD5 could not be validated for user operator)" or - in worst case - "Unexpected authentication problem", which is waaay more helpful, so I submit this trivial, but useful improvement.
