[jira] [Created] (CASSANDRA-16945) Multiple full sources can be select unexpectedly for bootstrap streaming

Yifan Cai created CASSANDRA-16945:
-------------------------------------

             Summary:  Multiple full sources can be select unexpectedly for bootstrap streaming
                 Key: CASSANDRA-16945
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16945
             Project: Cassandra
          Issue Type: Bug
          Components: Consistency/Bootstrap and Decommission
            Reporter: Yifan Cai
            Assignee: Yifan Cai


With CASSANDRA-14404, the RangeStreamer selects all endpoints as sources when using strict consistency and RF > endpoints count. In such case, the bootstrapping node is almost guaranteed to fail in the validation later. 

It is a change of behavior. Before the patch, in such case (i.e., higher RF) the bootstrapping node just pick one endpoint as source, since consistent range movement cannot be established. I'd propose to restore the old behavior.
