> Here is related code:
> {code}
>       handlePendingFilesForPreviousCheckpoints(bucketState.pendingFilesPerCheckpoint);
>       synchronized (bucketState.pendingFilesPerCheckpoint) {
>         bucketState.pendingFilesPerCheckpoint.clear();
>       }
> {code}
> The handlePendingFilesForPreviousCheckpoints() call should be enclosed inside the synchronization block. Otherwise during the processing of handlePendingFilesForPreviousCheckpoints(), some entries of the map may be cleared.
