ExecutorsTab

ExecutorsTab is a SparkUITab with executors prefix.

ExecutorsTab is created exclusively when SparkUI is initialized.

ExecutorsTab takes the parent SparkUI when created.

When created, ExecutorsTab creates the following pages and attaches them immediately:

• ExecutorsPage

• ExecutorThreadDumpPage

ExecutorsTab uses ExecutorsListener to collect information about executors in a Spark application.
