Subject [jira] [Commented] (CASSANDRA-12813) NPE in auth for bootstrapping node
Date Thu, 22 Feb 2018 03:54:02 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12813?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16372381#comment-16372381
] 

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.
