[jira] [Created] (KAFKA-6635) Producer close does not await pending transaction

Jason Gustafson created KAFKA-6635:
--------------------------------------

             Summary: Producer close does not await pending transaction
                 Key: KAFKA-6635
                 URL: https://issues.apache.org/jira/browse/KAFKA-6635
             Project: Kafka
          Issue Type: Bug
          Components: producer 
            Reporter: Jason Gustafson
            Assignee: Jason Gustafson


Currently close() only awaits completion of pending produce requests. If there is a transaction ongoing, it may be dropped. For example, if one thread is calling {{commitTransaction()}} and another calls {{close()}}, then the commit may never happen even if the caller is willing to wait for it (by using a long timeout). What's more, the thread blocking in {{commitTransaction()}} will be stuck since the result will not be completed once the producer has shutdown.
