      Description

      we are seeing an issue were we intermittently (every couple of hours) get and error with certain topics. They stop working and producers give a LeaderNotFoundException.
      When we then try to use kafka-topics.sh to describe the topic we get the error below.

      Error while executing topic command : next on empty iterator
      {{
      [2016-03-15 17:30:26,231] ERROR java.util.NoSuchElementException: next on empty iterator

      at kafka.admin.TopicCommand.main(TopicCommand.scala)
      (kafka.admin.TopicCommand$)
      }}

      if we delete the topic, then it will start to work again for a while
      We can't see anything obvious in the logs but are happy to provide if needed
