Yu Gan updated KAFKA-6404:
--------------------------
    Description: 
pls wait for some minutes, i'm editing...

kafka broker version: 0.10.0.1
cluster level: 240 nodes
situatition: someone use high released version (such as 0.11.x) of 
bin/kafka-console-consumer.sh with parameter "--zookeeper" to continuously 
consume a topic with partitions spread all the brokers
phenomenon: 
1.broker server log:
errors like: 1) Connection to 2 was disconnected before the response was read;
2) Shrinking ISR for partition [abc, 21] from 33,13,14 to 33;
3) ERROR Processor got uncaught exception. (kafka.network.Processor) 
java.nio.BufferUnderflowException
2.common consumers keeping in rebalance status:
errors like:
1) c.p.b.f.l.c.FiberTopoWorkerThread : got uncaught exception
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 session.timeout.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.
2) java.lang.IllegalStateException: Correlation id for response (1246203) does 
not match request (1246122)


bad results: kafka cluster in sick
