Varsha Mahadevan commented on CASSANDRA-12813:
----------------------------------------------
Is there a known workaround to get past this issue? I have a node to bootstrap
into my cluster but cannot immediately undertake a version upgrade of
cassandra. My node bootstrap does not succeed due to this error.

> I have a node that has been joining for around 24 hours. My application is
> configured with the IP address of the joining node in the list of nodes to
> connect to (ruby driver), and I have been getting around 200 events of this
> NPE per hour. I removed the IP of the joining node from the list of nodes
> for my app to connect to and the errors stopped.
