Subject [jira] [Commented] (CASSANDRA-4538) Strange CorruptedBlockException when massive insert binary data
Date Tue, 14 Aug 2012 17:59:38 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13434333#comment-13434333
] 

Cathy Daw commented on CASSANDRA-4538:
--------------------------------------

I tried to reproduce on a 32-bit debian squeeze medium instance on EC2 and could not get the
error.  I wonder if you are dealing with a permanently corrupted as the result of a intermittent
bug.  Can you drop this column family and keyspace, recreate them, and then re-run the test?
 Can you also paste the DDL to create the column family?
