Subject Error during cleanup
Date Tue, 08 Oct 2013 07:08:16 GMT

When running cleanup on a node with C* 2.0.1, I got the following error:

cassandra01 - Error during cleanup:
java.util.concurrent.ExecutionException: java.lang.ClassCastException:$EmptyCompactionScanner cannot
be cast to

However, cleanup appears to have worked, since the size of the data on that
particular node has decreased.

Is this an error to worry about?
