             Summary: Make task interruption optional on Gobblin task cancellation
                 Key: GOBBLIN-1355
                 URL: https://issues.apache.org/jira/browse/GOBBLIN-1355
             Project: Apache Gobblin
          Issue Type: Improvement
          Components: gobblin-core
    Affects Versions: 0.16.0
            Reporter: Sudarshan Vasudevan
            Assignee: Abhishek Tiwari
             Fix For: 0.16.0


Currently, the thread running a Gobblin task is interrupted when a task cancellation is invoked. When such a task is managing a Kafka consumer for instance, the interrupt leaves the consumer instance in a corrupt state, particularly if the consumer is in the middle of a poll() when the interrupt occurs. This in turn prevents the subsequent clean up of the consumer instance resulting in a potential resource leak. 

With this change, we provide the option to avoid interrupting the thread in aforementioned scenarios and let the poll() return before the thread is shutdown.
