    [ https://issues.apache.org/jira/browse/CASSANDRA-4345?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13296076#comment-13296076

Jonathan Ellis commented on CASSANDRA-4345:

> Copied a config from an existing node and fired up a new node, which happily inserted
