[CX] Subsequent Rebalance Fails After Cancellation With Secondary Indexes

If a rebalance is canceled during certain stages of rebalancing secondary indexes, any subsequent rebalance will fail with the exception:

HYR0081: File (file_path) is already mapped

This happens due to improper cleanup from the previously cancelled rebalance attempt.

Note that in other stages of the rebalance, the cancellation might cause AnalyticsDriver process to restart to ensure data integrity. When that happens, the exception will not be encountered.
