-----------------------------
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.
