             Summary: Set average fetch time in the KafkaExtractor even when 
metrics are disabled
                 Key: GOBBLIN-1100
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-1100
             Project: Apache Gobblin
          Issue Type: Bug
            Reporter: Hung Tran


The KafkaExtractor close method only calls the 
KafkaExtractorStatsTracker#emitTrackingEvents method when metrics 
instrumentation is enabled. This method calls 
KafkaExtractorStatsTracker#generateTagsForPartitions, which has the side effect 
of setting the average fetch time in the WorkUnitState. The average fetch time 
is required for the work unit packing to pack optimally.

 

Add a call to KafkaExtractorStatsTracker#generateTagsForPartitions in 
KafkaExtractor#close when metrics instrumentation is disabled to restore the 
behavior that existed prior to the KafkaExtractorStatsTracker refactoring.
