Wenchen Fan 3823dc88d3 [SPARK-22252][SQL][FOLLOWUP] Command should not be a LeafNode ... ## What changes were proposed in this pull request? This is a minor folllowup of #19474 . #19474 partially reverted #18064 but accidentally introduced a behavior change. `Command` extended `LogicalPlan` before #18064 , but #19474 made it extend `LeafNode`. This is an internal behavior change as now all `Command` subclasses can't define children, and they have to implement `computeStatistic` method. This PR fixes this by making `Command` extend `LogicalPlan` ## How was this patch tested? N/A Author: Wenchen Fan <wenchen@databricks.com> Closes #19493 from cloud-fan/minor.		2017-10-13 10:49:48 -07:00
