> NotLeaderForPartitionException is logged at the ERROR level with a full stack
> trace. But really this is just an informational message on the server when a
> client with stale metadata sends requests to the wrong leader for a
> partition. This floods the logs either if there are many clients or few
> clients sending many topics (migration tool or mirror maker). This should
> probably be logged at WARN and without the stack trace
