[SPARK-23385][CORE] Allow SparkUITab to be customized adding in Sparkâ¦
â¦Conf and loaded when creating SparkUI
## What changes were proposed in this pull request?
It would be nice if there was a mechanism to allow to add customized
SparkUITab (embedded like Jobs, Stages, Storage, Environment, Executors,...) to
be registered through SparkConf settings. This would be more flexible when we
need display some special information in UI rather than adding the embedded one
by one and wait community to merge.
I propose to introduce a new configuration option, spark.extraUITabs, that
allows customized WebUITab to be specified in SparkConf and registered when
SparkUI is created. Here is the proposed documentation for the new option:
> A comma-separated list of classes that implement SparkUITab; when
initializing SparkUI, instances of these classes will be created and registered
to the tabs array in SparkUI. If a class has a two-argument constructor that
accepts a SparkUI and AppStatusStore, that constructor will be called; If a
class has a single-argument constructor that accepts a SparkUI; otherwise, a
zero-argument constructor will be called. If no valid constructor can be found,
the SparkUI creation will fail with an exception.
## How was this patch tested?
1. Offerred a unit test.
2. Check the WebUI to see a new tab called "Test" via
`bin/spark-shell` --master local --driver-class-path
/path/spark-core_2.11-*-tests.jar --conf
`spark.extraUITabs=org.apache.spark.ui.TestUITab
