Note: this is for an older version : We are running kafka_2.9.2-0.8.1
When attempting to run the kafka-console-consumer.bat against an existing topic on windows7 we receive "failed to add leader" and "NotLeaderForPartition" exceptions
Here is the command line
set GROUP=group1234
kafka-console-consumer.bat --group %GROUP% --zookeeper localhost:2181 --topic calls --from-beginning
Here are the errors:

Note: Zookeeper is seeing the Consumer attempt to connect: I go into zkCli and can see the new group1234

In case there were corruption on the topic, I just dropped it in ZK and then recreated it via kafka-topics.bat. Here is the new ZK output
