             Summary: Kafka Connect: Offset committing times out before expected
                 Key: KAFKA-4942
                 URL: https://issues.apache.org/jira/browse/KAFKA-4942
             Project: Kafka
          Issue Type: Bug
            Reporter: Stephane Maarek
            Priority: Critical


I run a connector that deals with a lot of data, in a kafka connect cluster

When the offsets are getting committed, I get the following:
[2017-03-23 03:56:25,134] INFO WorkerSinkTask{id=MyConnector-1} Committing 
offsets (org.apache.kafka.connect.runtime.WorkerSinkTask)
[2017-03-23 03:56:25,135] WARN Commit of WorkerSinkTask{id=MyConnector-1} 
offsets timed out (org.apache.kafka.connect.runtime.WorkerSinkTask)

If you look at the timestamps, they're 1 ms apart. My settings are the 
following: 
        offset.flush.interval.ms = 120000
        offset.flush.timeout.ms = 60000
        offset.storage.topic = _connect_offsets

It seems the offset flush timeout setting is completely ignored for the look of 
the logs. I would expect the timeout message to happen 60 seconds after the 
commit offset INFO message, not 1 millisecond later.
