----------------------------

             Summary: Wrong warning of "WARN Master: App app-xxx requires more resource than any of Workers could have."
                 Key: SPARK-31921
                 URL: https://issues.apache.org/jira/browse/SPARK-31921
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 3.0.0
            Reporter: wuyi


When start spark-shell using local cluster mode, e.g. ./bin/spark-shell --master "local-cluster[2, 1, 1024]", there will be a warning:

 
{code:java}
20/06/06 22:09:09 WARN Master: App app-20200606220908-0000 requires more resource than any of Workers could have.
{code}

which means the application can not get enough resources to launch at least one executor.

But that's not true since we can successfully complete a job.
