Vivekanand Koya updated CASSANDRA-20984:
----------------------------------------
    Description: 
On version mismatch and/or protocol incompatibility between the two 
communicating nodes, cassandra server does not handle the errors correctly. 
There is no proper error handling when ClassCastException occurs, since it is 
not consistently reproducible. 

In 
[https://lists.apache.org/thread/ykkwhjdpgyqzw5xtol4v5ysz664bxxl3.,|https://lists.apache.org/thread/ykkwhjdpgyqzw5xtol4v5ysz664bxxl3.]
 the "Stream failed" message points to a streaming operation, which is used for 
processes like node repairs or adding new nodes (bootstrapping).

similar Jira that was already raised - 
https://issues.apache.org/jira/browse/CASSANDRA-19218.  Not sure what to do 
with this JIRA. Looks like a duplicate.
