-----------------------------------------------------------------
I can't reproduce this with either the Hector test or with a basic Thrift-based
test that does the same operations in a loop. Can you reproduce this reliably?
Perhaps there's a specific way to run the Hector test that reproduces it?
Just looking at the stacktrace, it seems like the NPE is due to trying to call
{{modifications.put()}} with a null key, which would require that the existing
row's {{CFMetadata}} has a null {{cfId}}, and I'm not sure how that can happen.
