[jira] [Commented] (CASSANDRA-9332) NPE when creating column family via thrift

["Tyler Hobbs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-9332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14544377#comment-14544377 ] 

Tyler Hobbs commented on CASSANDRA-9332:
----------------------------------------

I can't reproduce this with either the Hector test or with a basic Thrift-based test that does the same operations in a loop.  Can you reproduce this reliably?

Just looking at the stacktrace, it seems like the NPE is due to trying to call {{modifications.put()}} with a null key, which would require that the existing row's {{CFMetadata}} has a null {{cfId}}, and I'm not sure how that can happen.
