> Hive uses the same context object for the hooks for a given query, which results in some synchronisation issues in HiveProtoLoggingHook:
> * post event arrives before pre event processing starts, since the object is shared, the event type for both events is post event, causes skipping of pre event publishing.
> * Causes concurrent modification exception while iterating perf object.
> The queue name is extracted does not consider execution context, fix to extract queue name from different config based on the execution mode.
