Spark Authentication can be configured using a shared secret configured by the spark.authenticate configuration parameter. The authentication process is essentially a handshake between Spark and the other party to ensure they have the same shared secret and can be allowed to communicate. If the shared secret does not match, they will not be allowed to communicate.
- Go to the tab.
