This exception seems to be consistently thrown during the data load phase. It appears in compute-table-stats.log.

ctas_cancel is a table that gets used by query_test/test_cancellation.py

This doesn't seem to break anything (data laoding completes and tests pass), but it's vexing that we part of our standard data load process produces exceptions in any log file.

Please feel free to mark this as invalid if this is not really an issue.
