Subject: [PATCH] [SPARK-13810][CORE] Add Port Configuration Suggestions on
Bind Exceptions
## What changes were proposed in this pull request?
Currently, when a java.net.BindException is thrown, it displays the following message:
java.net.BindException: Address already in use: Service '$serviceName' failed after 16 retries!
This change adds port configuration suggestions to the BindException, for example, for the UI, it now displays
java.net.BindException: Address already in use: Service 'SparkUI' failed after 16 retries! Consider explicitly setting the appropriate port for 'SparkUI' (for example spark.ui.port for SparkUI) to an available port or increasing spark.port.maxRetries.
## How was this patch tested?
Manual tests
Author: Bjorn Jonsson <bjornjon@gmail.com>
Closes #11644 from bjornjon/master.
