> When Ambari agents are configured to run with a non-root user, if kerberos is
> enabled, Kafka service check experiences errors in the logs which indicate
> that the check is attempting to create a topic that already exists. However
> the true failure, which isn't in the logs but captured in an error variable,
> demonstrates the culprit (see below):
> [2017-11-22 05:12:57,029] WARN SASL configuration failed:
> javax.security.auth.login.LoginException: No password provided Will continue
> connection to Zookeeper server without SASL authentication, if Zookeeper
> server allows it. (org.apache.zookeeper.ClientCnxn)
> Exception in thread "main"
> org.I0Itec.zkclient.exception.ZkAuthFailedException: Authentication failure
> at org.I0Itec.zkclient.ZkClient.waitForKeeperState(ZkClient.java:947)
> at org.I0Itec.zkclient.ZkClient.waitUntilConnected(ZkClient.java:924)
> at org.I0Itec.zkclient.ZkClient.connect(ZkClient.java:1231)
> at org.I0Itec.zkclient.ZkClient.<init>(ZkClient.java:157)
> at org.I0Itec.zkclient.ZkClient.<init>(ZkClient.java:131)
> at kafka.utils.ZkUtils$.createZkClientAndConnection(ZkUtils.scala:115)
> at kafka.utils.ZkUtils$.apply(ZkUtils.scala:97)
> at kafka.admin.TopicCommand$.main(TopicCommand.scala:56)
> at kafka.admin.TopicCommand.main(TopicCommand.scala)
> This occurs because a prior check to see if the topic exists is not executed
> as the kafka user. A subsequent call to create the topic does execute as that
> user. The first check should also execute as the kakfa user. Also Ambari
> should immediately raise a failure if an error occurs during the topic check
> and show that error in the logs.
