kafka報錯： org.apache.kafka.clients.consumer.CommitFailedException: 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.apache
這個是由於：一個consumer在生產消息，另外一個consumer在消費它的消息，他們不能在一個groupid 下面，更改其中一個的group id 便可session
