[jira] [Commented] (CASSANDRA-3306) Error in
LeveledCompactionStrategy
[ https://issues.apache.org/jira/browse/CASSANDRA-3306?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13144240#comment-13144240 ]
Sylvain Lebresne commented on CASSANDRA-3306:
---------------------------------------------
I'll note that more info have been added to the messages thrown by the exception here in 1.0.1. So if someone can reproduce this issue on 1.0.1, it would be useful to get the stacktrace (the full system.log would actually be even better).
