[jira] [Created] (HIVE-20383) Invalid queue name and synchronisation issues in hive proto events hook.

Harish Jaiprakash created HIVE-20383:
----------------------------------------

             Summary: Invalid queue name and synchronisation issues in hive proto events hook.
                 Key: HIVE-20383
                 URL: https://issues.apache.org/jira/browse/HIVE-20383
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
            Reporter: Harish Jaiprakash
            Assignee: Harish Jaiprakash
         Attachments: HIVE-20383.01.patch

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.
