--------------------------------------

             Summary: ArrayIndexOutOfBounds exception may be thrown while processing events
                 Key: RANGER-4129
                 URL: https://issues.apache.org/jira/browse/RANGER-4129
             Project: Ranger
          Issue Type: Bug
          Components: tagsync
            Reporter: Abhay Kulkarni
            Assignee: Abhay Kulkarni


If AtlasTagSource.buildAndUploadServiceTags() is called with empty AtlasTagSource.atlasEntityWithTags list, then an ArrayIndexOutOfBounds exception is thrown when AtlasTagSource.messages list is read. This may happen when the first notification processed by tagsync process is of type ENTITY_DELETE.

This Jira also fixes a potential issue if the Kafka queue contains only a large number of notifications not expected to be handled by tagsync. In such cases, tagsync will not acknowledge receipt and it may cause back-pressure on Kafka queue.
