Follower take some time to become the leader in case leader is down . you can
build retry logic to around this to handle this situation .

Hi,
I have a 3 node kafka cluster (replication-factor : 3), suddenly one of the
node in the cluster was down and i started seeing the
NotLeaderForPartitionException exception in my application logs when
sending the message to one of the topics, however for some of the topics i
am able post and consume messages.
I could see this problem lasting until all the kafka servers are restarted,
after the restart things are all ok.
Now, my question is, why not the new leader not elected for those topics
but keep throwing the same NotLeaderForPartitionException exception and how
to get the new leader election happen for these topics.
