Shubham Gupta commented on SPARK-21398:
---------------------------------------
I am using yarn so , I called using
`api/v1/applications/[app-id]/[attempt-id]/allexecutors` , and in my scala
script I am calling it using the `scala.io.Source.fromURL(url)`.
I am getting the respective JSON of executor summary but all the time I am
fetching the data I am getting the same JSON besides that I have a lot of new
executors allocated and deallocated.
> Data on Rest end point is not updating after first fetch
