Subject [jira] [Commented] (CASSANDRA-6310) MarshalException: cannot parse 'column1' as hex bytes when inserting data exported from 2.0.0 to 1.2.9 using json2sstable
Date Thu, 07 Nov 2013 16:49:22 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-6310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13816119#comment-13816119
] 

Jonathan Ellis commented on CASSANDRA-6310:
-------------------------------------------

Clarification: sstableloader can handle 1.2 -> 2.0, but not the other way around.
