> Project: Apache AsterixDB
> Issue Type: Bug
> Components: TX - Transactions
> Reporter: Murtadha Hubail
> Assignee: Murtadha Hubail
> Priority: Critical
>
> When a metadata transaction is aborted, the number of active operations on
> the primary index are decremented twice, one time when the job abort log is
> written and the other when the transaction completes its abortion. This will
> result in the following exception when the index is accessed the next time:
> {code:java}
> Caused by: org.apache.hyracks.api.exceptions.HyracksDataException: The number
> of active operations cannot be negative!
