can any one help me out why i am getting the above issue in zookeeper ??

[jlevy8]

What version of CruiseControl/Kafka/Zookeeper are you running?

Seems like your SSL Configurations are missing.
Have you tried passing the parameters in as suggested in #1323?

Specifically these JVM System Properties

-Dzookeeper.client.secure=true \
-Dzookeeper.clientCnxnSocket=org.apache.zookeeper.ClientCnxnSocketNetty \
-Dzookeeper.ssl.keyStore.location=<ks location> \
-Dzookeeper.ssl.keyStore.password=<ks password> \
-Dzookeeper.ssl.trustStore.location=<ts location> \
-Dzookeeper.ssl.trustStore.password=<ts password>
