Nick Bailey commented on CASSANDRA-5310:
----------------------------------------
Can we add some additional error messaging around this maybe? If we get
UnavailableException when looking up the 'cassandra' user log that we have to
use quorum for that user lookup? It's extremely confusing to run into this in
the wild.
