RE: Migrating from 07.1 .100

[Subhash Agrawal]

Hi,
I currently embed kafka 0.7.1 in my java process. To support SSL, we have 
decided to upgrade Kafka to 0.10.0.
After upgrade, I am seeing following error during kafka startup.

java.lang.NullPointerException
                at kafka.utils.Throttler.<init>(Throttler.scala:45)
                at kafka.log.LogCleaner.<init>(LogCleaner.scala:75)
                at kafka.log.LogManager.<init>(LogManager.scala:66)
                at 
kafka.server.KafkaServer.createLogManager(KafkaServer.scala:609)
                at kafka.server.KafkaServer.startup(KafkaServer.scala:183)

Has anybody seen this error? If I run kafka externally, then I don't see this 
error.

Thanks
Subhash A.

Hi,
I am currently using Kafka 0.7.1 without zookeeper. We have single node kafka 
server.
To enhance security, we have decided to support SSL. As 0.7.1 version does not 
support SSL,
we are upgrading to latest version 0.10.0.0. We noticed that with the latest 
version, it is
mandatory to use zookeeper.

Is there any way I can use Kafka 0.10 or 0.9 version without zookeeper?

Thanks
Subhash A.
