Subject [jira] [Updated] (CASSANDRA-2760) NPE in sstable2json
Date Sat, 23 Jun 2012 00:07:43 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-2760?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jason Brown updated CASSANDRA-2760:
-----------------------------------

    Attachment: 0001-cassandra-2760.patch

Instead of trying to process an unknown column family (and exiting with an exception), load
the Descriptor at the top of the export process and check to see if the keyspace/column family
exists inside the current cassandra setup. If not, print a warning message and exit.
