edwinalu opened a new pull request #23340: [SPARK-23431][CORE] Expose the new executor memory metrics at the stage level
URL: https://github.com/apache/spark/pull/23340
 
 
   ## What changes were proposed in this pull request?
   
   Collect and show the new executor memory metrics for each stage, to provide more information on how memory is used per stage. Peak values for metrics are show for each stage. For executor summaries for each stage, the peak values per executor are also shown.
   
   ## How was this patch tested?
   
   Added new unit tests.

> Collect and show the new executor memory metrics for each stage, to provide more information on how memory is used per stage.
> Modify the AppStatusListener to track the peak values for JVM used memory, execution memory, storage memory, and unified memory for each executor for each stage.
> Add the peak values for the metrics to the stages REST API. Also add a new stageSummary REST API, which will return executor summary metrics for a specified stage:
> {code:java}
> curl http://<spark history server>:18080/api/v1/applications/<application id>/<application attempt/stages/<stage id>/<stage attempt>/executorSummary{code}
> This is a subtask for SPARK-23206. Please refer to the design doc for that ticket for more details.
