[jira] [Created] (SPARK-29373) DataSourceV2: Commands should not submit a spark job.

Terry Kim created SPARK-29373:
---------------------------------

             Summary: DataSourceV2: Commands should not submit a spark job.
                 Key: SPARK-29373
                 URL: https://issues.apache.org/jira/browse/SPARK-29373
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Terry Kim


DataSourceV2 Exec classes (ShowTablesExec, ShowNamespacesExec, etc.) all extend LeafExecNode. This results in running a job when executeCollect() is called. This breaks the previous behavior [SPARK-19650|https://issues.apache.org/jira/browse/SPARK-19650].

A new command physical operator will be introduced form which all V2 Exec classes derive to avoid running a job.
