---------------------------------------

             Summary: Ambiguous error message: "You must specify one and only one PRIMARY KEY"
                 Key: CASSANDRA-5875
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5875
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Jacob Rhoden
            Priority: Minor


Minor issue, but might be beneficial for new people. I was _missing_ a primary key but thought it meant there was more than one primary key, and was confused for a minute. Here is the current error: 

Caused by: com.datastax.driver.core.exceptions.InvalidQueryException: You must specify one and only one PRIMARY KEY
	at com.datastax.driver.core.ResultSetFuture.convertException(ResultSetFuture.java:252)
	at com.datastax.driver.core.ResultSetFuture$ResponseCallback.onSet(ResultSetFuture.java:119)
	at com.datastax.driver.core.RequestHandler.setFinalResult(RequestHandler.java:202)
	at com.datastax.driver.core.RequestHandler.onSet(RequestHandler.java:319)

Recommend considering two different error messages, ie:

 - No primary keys were found, when exactly one is required.
 - Multiple primary keys were found, when exactly one may be specified.
