> Add Port Configuration Suggestions on Bind Exceptions
> -----------------------------------------------------
>
> Key: SPARK-13810
> URL: https://issues.apache.org/jira/browse/SPARK-13810
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Bjorn Jonsson
> Priority: Minor
> Labels: supportability
>
> When a java.net.BindException is thrown in startServiceOnPort in Utils.scala,
> it displays the following message, irrespective of the port being used:
> java.net.BindException: Address already in use: Service '$serviceName' failed
> after 16 retries!
> For supportability, it would be useful to add port configuration suggestions
> for the related port being used. For example, if the Spark UI exceeds
> spark.port.maxRetries, users should see:
> java.net.BindException: Address already in use: Service 'SparkUI' failed
> after 16 retries! Consider setting spark.ui.port to an available port or
> increasing spark.port.maxRetries.
