Description
Spark standalone master web UI show "Alive workers" worker number, "Alive Workers" total core, total used cores and "Alive workers" total memory, memory used.
But the JSON API page "http://MASTERURL:8088/json" shows "all workers" worker number, core, memory number.
This webUI data is not sync with the JSON API.
The proper way is to sync the number with webUI and JSON API.
