Lovenish goyal created KAFKA-7145:
-------------------------------------

             Summary: Consumer thread getting stuck in hasNext() method
                 Key: KAFKA-7145
                 URL: https://issues.apache.org/jira/browse/KAFKA-7145

          Components: clients
    Affects Versions: 0.10.0.1, 0.9.0.1

Consumer thread is getting stuck at *hasNext()* method.

we are using ConsumerIterator for same and below is the code snipped 

 
{code:java}
ConsumerIterator mIterator;
List<KafkaStream<byte[], byte[]>> streams = mConsumerConnector.createMessageStreamsByFilter(topicFilter);
KafkaStream<byte[], byte[]> stream = streams.get(0);
mIterator = stream.iterator();

{code}
 

When i manually check via [Kafdrop|https://github.com/HomeAdvisor/Kafdrop] I am seeing 'No message found' message.I have tried same with both kafka version 9 & 10 and getting same issue.
