>            Reporter: Stephane Maarek
> On Kafka
> 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:
> {code}
> [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)
> {code}
> If you look at the timestamps, they're 1 ms apart. My settings are the following: 
> {code}
> 	offset.flush.interval.ms = 120000
> 	offset.flush.timeout.ms = 60000
> 	offset.storage.topic = _connect_offsets
> {code}
> 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.
