    Auto-commit of offsets fail, and not recover forever...

    * Auto-commit of offsets fail, and not recover **forever**. at sendOffsetCommitRequest,
 while "generation equal NULL",  ConsumerCoordinator request will fail always.  it maybe a
bug. error log below:
    has more and more warn log ....
    "2017-12-01 22:08:39.112 WARN  pool-390-thread-1#1 (ConsumerCoordinator.java:626) - Auto-commit
of offsets {drawing_gift_sent-1=OffsetAndMetadata{offset=32150359, metadata=''}} failed for
group gift_rich_audience_write: Commit cannot be completed since the group has already rebalanced
and assigned the partitions to another member. This means that the time between subsequent
calls to poll() was longer than the configured max.poll.interval.ms, which typically implies
that the poll loop is spending too much time message processing. You can address this either
by increasing the session timeout or by reducing the maximum size of batches returned in poll()
with max.poll.records."
