Error during cleanup
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?

I'm hoping it will show up in Cassandra's system.log, but since it's
triggered through JMX, it's possible that it will not.

No, but I may be able to get one for you if the issue is reproducible when
I trigger another cleanup.
I originally issued the cleanup on the node via OpsCenter Community Edition
3.2.2
If I issue another cleanup, can you give me the rough steps for how to get
the stacktrace?

Do you have a complete stacktrace available?
