> Support task Metrics Distributions and executor Metrics Distributions in the
> REST API call for a specified stage
> ----------------------------------------------------------------------------------------------------------------
>
> Key: SPARK-34488
> URL: https://issues.apache.org/jira/browse/SPARK-34488
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 3.0.2
> Reporter: Ron Hu
> Assignee: Ron Hu
> Priority: Major
> Fix For: 3.2.0
>
> Attachments: executorMetricsDistributions.json,
> taskMetricsDistributions.json
>
>
> For a specific stage, it is useful to show the task metrics in percentile
> distribution. This information can help users know whether or not there is a
> skew/bottleneck among tasks in a given stage. We list an example in
> [^taskMetricsDistributions.json]
> Similarly, it is useful to show the executor metrics in percentile
> distribution for a specific stage. This information can show whether or not
> there is a skewed load on some executors. We list an example in
> [^executorMetricsDistributions.json]
>
> We define withSummaries query parameter in the REST API for a specific stage
> as:
> applications/<application_id>/<application_attempt/stages/<stage_id>/<stage_attempt>?withSummaries=[true|false]&quantiles=0.0,0.25,0.5,0.75,1.0
> * When withSummaries=true, both task metrics in percentile distribution and
> executor metrics in percentile distribution are included in the REST API
> output. The default value of withSummaries is false, i.e. no metrics
> percentile distribution will be included in the REST API output.
> * Query parameter quantiles define the quantiles we use to calculate metrics
> distributions. It takes effect only when {{withSummaries=true.}} Its
> default value is {{0.0,0.25,0.5,0.75,1.0.}}
