[jira] [Resolved] (SPARK-3602) Can't run cassandra_inputformat.py
[ https://issues.apache.org/jira/browse/SPARK-3602?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sean Owen resolved SPARK-3602.
------------------------------
Resolution: Not A Problem
I think this is due to mismatching Hadoop libs, or at least is stale enough at this point that I think it should be closed.
