             Summary: Add a task status filter for taskList in REST API
                 Key: SPARK-28183
                 URL: https://issues.apache.org/jira/browse/SPARK-28183
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core, Web UI
    Affects Versions: 3.0.0
            Reporter: Lantao Jin


We have a scenario that our application needs to query failed tasks by REST API {{/applications/[app-id]/stages/[stage-id]/[stage-attempt-id]/taskList}} when Spark job is running. In a large Stage, it may contain hundred thousands tasks totally. Although it offers a pagination query via {{?offset=[offset]&length=[len]}}, it still faces two disadvantages:
1. App still needs to query out all tasks. It consumes much unnecessary memory and time both in Spark and App side.
2. Pagination query via {{?offset=[offset]&length=[len]}} makes the logic much complex and it still needs to handle all tasks.
