> 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.
