Little improvement on the messages of the exceptions thrown by ExternalClient
-----------------------------------------------------------------------------
Key: CASSANDRA-4177
URL: https://issues.apache.org/jira/browse/CASSANDRA-4177
Project: Cassandra
Issue Type: Improvement
Reporter: Michał Michalski
Priority: Trivial
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.
