慣れないとKeystore/Truststoreを設定するのは面倒なので、Knoxのを使いまわします。

Advanced zeppelin-config
zeppelin.ssl = true
zeppelin.ssl.key.manager.password = knox
zeppelin.ssl.keystore.password = knox
zeppelin.ssl.keystore.path = /etc/security/serverKeys/keystore.jks

cp /usr/hdp/current/knox-server/data/security/keystores/gateway.jks /etc/security/serverKeys/keystore.jks
chmod a+r /etc/security/serverKeys/keystore.jks
