-----------------------------------
Assignee: Terry Kim
> 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
> Assignee: Terry Kim
> Priority: Blocker
>
> 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.
