Subject Kafka Partition Leader -1
Date Thu, 07 Nov 2019 09:18:53 GMT
Hello Experts ,  We are observing issues in Partition(s) when the Kafka
broker is down & the Partition Leader Broker ID set to -1.

Kafka Version 2.2.0
Total No Of Brokers: 24
Total No Of Partitions: 48
Replication Factor: 2
Min In sync Replicas: 1


Partition                                             Leader
 Replicas           In Sync Replicas

See above the Partition 41 leader set to -1 ,  the replicas exist in 18,24.
The broker id 24 went down for due to Too many open files.

Q: Why is it not electing the broker 18 as a leader for Partition 41?

Had a similar problem in Past, after fixing the broker the partition shows
correct leader.

Kafka Properties:

default.replication.factor = 2

unclean.leader.election.enable = true

min.insync.replicas = 1

num.partitions = 48



Zookeeper Active Broker ID's:

[zk: localhost:2181(CONNECTED) 1] ls /kafka.test/brokers/ids

[1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 3, 4, 5, 6, 7,
8, 9]

[zk: localhost:2181(CONNECTED) 2]

Restarting ZK also didn't help.

Pls advise! How to fix this? Why is this happening?
