In the middle of a leadership election, there is currently no leader...

[Josh J]

Hi,

I'm running three kafka brokers. I receive the following when using the
producer

panic: kafka server: In the middle of a leadership election, there is
currently no leader for this partition and hence it is unavailable for
writes.


Though the describe topic shows a leader for each partition. What's
happening here to make it unavailable for writes?
