Thanks for clarification. I am seeing strange behavior in that case, When I set min.insync.replicas=2 in my server.properties (restart the server) and set the acks=all on producer, I am still able to publish to topic even when only leader is up (none of followers are alive). With this configuration I was hoping to see NotEnoughReplicasException.
When I set min.insync.replicas=2 specifically on my topic and set the acks=all on producer, I get error NotEnoughReplicasException when less than 2 replicas are live. Because of this behavior I thought min.insync.replicas=2 in my server.properties does not work and we needed it at explicit topic level. This looks like bug?? Anyone facing this issue. -----Original Message----- From: Todd Palino [mailto:tpal...@gmail.com] Sent: Monday, March 06, 2017 6:48 PM To: users@kafka.apache.org Subject: Re: Clarification on min.insync.replicas Default broker configurations do not show in the topic overrides (which is what you are showing with the topics tool). It is more accurate to say that the min.insync.replicas setting in your server.properties file is what will apply to every topic (regardless of when it is created), if there exists no topic override for that configuration for that config. -Todd On Mon, Mar 6, 2017 at 4:38 PM, Shrikant Patel <spa...@pdxinc.com> wrote: > Hi All, > > Need details about min.insync.replicas in the server.properties. > > I thought once I add this to server.properties, all subsequent topic > create should have this as default value. > > C:\JAVA_INSTALLATION\kafka\kafka_2.11-0.10.1.1>bin\windows\kafka-topic > s.bat --zookeeper localhost:2181/chroot/cluster1 --create --topic test > --partition 3 --replication-factor 3 Created topic "test". > > C:\JAVA_INSTALLATION\kafka\kafka_2.11-0.10.1.1>bin\windows\kafka-topic > s.bat --zookeeper localhost:2181/chroot/cluster1 --describe --topic > test > Topic:test PartitionCount:3 ReplicationFactor:3 Configs: > > No min.insync.replicas is set on the topic. > > Why do I have explicit provide this configuratoin when creating topic? > So whats the purpose of this in server.properties?? > > C:\JAVA_INSTALLATION\kafka\kafka_2.11-0.10.1.1>bin\windows\kafka-topic > s.bat --zookeeper localhost:2181/chroot/cluster1 --create --topic test > --partition 3 --replication-factor 3 --config min.insync.replicas=3 > Created topic "test". > > C:\JAVA_INSTALLATION\kafka\kafka_2.11-0.10.1.1>bin\windows\kafka-topic > s.bat --zookeeper localhost:2181/chroot/cluster1 --describe --topic > test > Topic:test PartitionCount:3 ReplicationFactor:3 > Configs:min.insync.replicas=3 > Topic: test Partition: 0 Leader: 1 Replicas: 1,2,0 > Isr: 1,2,0 > Topic: test Partition: 1 Leader: 2 Replicas: 2,0,1 > Isr: 2,0,1 > Topic: test Partition: 2 Leader: 0 Replicas: 0,1,2 > Isr: 0,1,2 > > Thanks > Shri > > > > This e-mail and its contents (to include attachments) are the property > of National Health Systems, Inc., its subsidiaries and affiliates, > including but not limited to Rx.com Community Healthcare Network, Inc. > and its subsidiaries, and may contain confidential and proprietary or > privileged information.
