Subject Re: Cassandra 1.0: Exception in compaction
Date Fri, 21 Oct 2011 09:25:59 GMT
I believe this is the same as
https://issues.apache.org/jira/browse/CASSANDRA-3306.

The initial reporter only got this exception with leveled compaction,
is it what you are
using too (to help narrow it down)? Also, are you using windows by any chance?
