The call to `getZkConnectStr` and `getTwillAppName` and `getTwillAppRunId`
will never return null based on the contract (no @Nullable) , hence call to
`getKafkaZKConnect` will never be null.
I was saying that either way, someone need to check whether call to
getKafkaZKConnect will return null if log collection is disabled, so why not
ask to isLogCollectionEnabled to check first.
