------------------------------------

             Summary: Consumer should cache topic partition info
                 Key: KAFKA-1143
                 URL: https://issues.apache.org/jira/browse/KAFKA-1143
             Project: Kafka
          Issue Type: Bug
            Reporter: Guozhang Wang
            Assignee: Guozhang Wang
             Fix For: 0.8.1


So that

1. It can check if rebalances are necessary when topic/partition watcher fires 
(they can be triggered for state change event even the data does not change at 
all).

2. Rebalance does not need to read again from ZK.
