Description

Steps:
1. Spark installed and running properly.
2. spark.ui.retainedTask=100000 ( it is default value )
3.Launch Spark shell ./spark-shell --master yarn
4. Create a spark-shell application with a single job and 500000 task
val rdd = sc.parallelize(1 to 500000, 500000)
rdd.count
5. Launch Job History Page and go to spark-shell application created above under Incomplete Task
6. Right click and got to Job page of the application and from there click and launch Stage Page
7. Launch the Stage Id page for the specific Stage Id for the above created job
8. Scroll down and check for the task msg above Pagination Panel
It Displays Task( 100000, Showing 500000)

Actual Result:
It displayed Task( 100000, Showing 500000)

Expected Result:
Since retainedTask=100000 and it should show 100000 task
So message should be Task( 500000, Showing 100000)
