Get replication and partition count of a topic

[Ankit Jain]

Hi All,


I want to get the replication and partition count of a topic. I tried the 
following piece of code:


        java.util.Set<String> topics = new HashSet<String>();
        topics.add("topicName");
        Set<TopicMetadata> topicMetadatas = 
AdminUtils.fetchTopicMetadataFromZk(JavaConversions.asScalaSet(topics), 
zkClient);
        Iterator<TopicMetadata> topicMetadataIterator = 
topicMetadatas.iterator();

        while (topicMetadataIterator.hasNext()) {
            topicMetadataIterator.next();
            topicMetadataIterator.next().
            Iterator<PartitionMetadata> partitionMetadataIterator = 
topicMetadataIterator.next().partitionsMetadata().iterator();

        }


But, the above code returning me the metadata of each partition and also 
replica details of each partition.


Is there any simple API available in kafka to get the partition and replica 
count for a topic.


Thanks,

Ankit
