(was: Hi [~Baohe Zhang] , This ticket proposes a new REST API:
http://<spark history
server>:18080/api/v1/applications/<application_id>/<application_attempt/stages/<stage_id>/<stage_attempt>/executorSummary.
It means to display the percentile distribution of peak memory metrics among
the executors used in a given stage. It can help Spark users debug/monitor a
bottleneck of a stage.
In the ticket https://issues.apache.org/jira/browse/SPARK-32446, it proposed to
add a REST API, which can display the percentile distribution of peak memory
metrics for all executors used in an application. The REST API is:
http://<spark history
server>:18080/api/v1/applications/<application_id>/<application_attempt>/executorSummary
Hence this ticket displays executorSummary for a given stage inside an
application. SPARK-32446 wants to display executorSummary for the entire
application. They are different.

> Reporter: Edward Lu
> Priority: Major
> Attachments: executorMetricsDistributions.json,

> [~angerszhuuu] and [~ron8hu] discussed a generic and consistent way for
> overall stages, i.e. endpoint /application/\{app-id}/stages. It can be:
> /application/\{app-id}/stages?details=[true|false]&status=[ACTIVE|COMPLETE|FAILED|PENDING|SKIPPED]&withSummaries=[true|false]&taskStatus=[RUNNING|SUCCESS|FAILED|KILLED|PENDING]
> where
> * query parameter details=true is to show the detailed task information
> within each stage. The default value is details=false;
> * query parameter status can select those stages with the specified status.
> When status parameter is not specified, a list of all stages are generated.
> * query parameter withSummaries=true is to show both task metrics summary
> information in percentile distribution (see example of a single stage in
> [^taskMetricsDistributions.json] ) and executor metrics summary information
> in percentile distribution (see example of a single stage in
> [^executorMetricsDistributions.json] ). The default value is
> withSummaries=false.
> * query parameter taskStatus is to show only those tasks with the specified
> status within their corresponding stages. This parameter can be set when
> details=true (i.e. this parameter will be ignored when details=false).
> The output is an aggregate of all stages meeting the filtering conditions for
> a given application.
