Hi, When running cleanup on a node with C* 2.0.1, I got the following error:
cassandra01 - Error during cleanup: javax.management.MBeanException: java.util.concurrent.ExecutionException: java.lang.ClassCastException: org.apache.cassandra.io.sstable.SSTableReader$EmptyCompactionScanner cannot be cast to org.apache.cassandra.io.sstable.SSTableScanner 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?
