{code}
My kafka java client cannot auto commit.After add some debug log,I found that
the coordinatorUnknown() function in
[ConsumerCoordinator.java#L604|https://github.com/apache/kafka/blob/0.10.2.1/clients/src/main/java/org/apache/kafka/clients/consumer/internals/ConsumerCoordinator.java#L604]
always returns true,and nextAutoCommitDeadline just increases infinitly.Should
there be a lookupCoordinator() after line 604 like in
[ConsumerCoordinator.java#L508|https://github.com/apache/kafka/blob/0.10.2.1/clients/src/main/java/org/apache/kafka/clients/consumer/internals/ConsumerCoordinator.java#L508].After
I add lookupCoordinator() next to line 604.The consumer can auto commit offset
properly.
