             Summary: Whether it is possible to support querying the status of a specific application in a subsequent version
                 Key: SPARK-40204
                 URL: https://issues.apache.org/jira/browse/SPARK-40204
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 2.4.6, 2.4.4
         Environment: Standalone Cluster Mode
            Reporter: bitao


The current SparkAppHandler cannot support obtaining the application status in Standalone Cluster mode. One way is to query the status of the specified Driver through the StandaloneRestServer, but it cannot query the status of the specified application. Is it possible to add a method (eg: handleAppStatus) to the StandaloneRestServer by asking the Master Send the RequestMasterState message to get the state of the specified application. The current MasterWebUI should do this, but the premise is that it needs to use the same RpcEnv as the Master Endpoint. Many times we care about the status of the application rather than the status of the Driver, so we hope to add this function in subsequent versions to support obtaining the status of the specified application in Standalone cluster mode.
