My kafka java client cannot auto commit.After add some debug log,I found that the coordinatorUnknown() function in ConsumerCoordinator.java#L604 always returns true,and nextAutoCommitDeadline just increases infinitly.Should there be a lookupCoordinator() after line 604 like in ConsumerCoordinator.java#L508?After I add lookupCoordinator() next to line 604.The consumer can auto commit offset properly.
