If you only have 1 replica, when the broker the replica is down, the
partition will have no leader. A broker can be down due to soft failures.

No it is not common/expected. It will be difficult to give you any
useful advise without your logs - please send over your state change
logs and broker logs.

So only one of the brokers have the data? i.e., with one partition.
Do you see errors in your broker log around that time? What do you see
in the kafka-state-change.log for that topic/partition?

I have 3 kafka brokers and I have created one topic with 1 partition and 1
replication (default options). All params are default. I was testing it
with heavy load and had a storm reading from this and suddenly the messages
stop. kafka's list topics script files then show the leader as -1.

Can you describe your set up in more detail and also if you can
reproduce this easily? This can happen when none of the replicas for a
partition are available, but cannot comment further without details.

Hi,
At times, some of kafka topics end up showing the leader as -1. After this,
the messages dont get added to the topic nor consumed. I tried digging into
why the leader turns -1 *(leader: -1)*
Is there a reason why this happens and how it can be resolved?
