Hey Alex,

Do you use ONE_TO_ONE or ONE_TO_MANY partition?

Regards,
Siyuan

Hey All,

We are using the 0.8.1 kafka operator and the ZK connection string has a chroot on it. We
get errors when launching and the app fails, is there a proper way in apex to append a chroot?


*the ip’s are masked with #, but that’s not how they appear in our code obviously*

When we add this to the property for ZK:


<property>
       <name>dt.operator.kafkaInputOperator.prop.consumer.zookeeper</name>
       <value>10.##.##.#:2181,10.##.##.##:2181,10.##.##.##:2181,10.##.##.#:2181/kafka2</value>
</property>



We get this error (connecting to a cluster without chroot it works fine):
