[jira] [Commented] (HIVE-9138) Add some explain to PTF operator

    [ https://issues.apache.org/jira/browse/HIVE-9138?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14316910#comment-14316910 ] 

Ashutosh Chauhan commented on HIVE-9138:
----------------------------------------

Sorry, missed on this one. Couple of questions:
* Whats the marker interface Explainable for? Can you add comments why is it necessary and who needs to implement it?
* Changes in ColumnPruner:  Are they related to explain or is it that datastructures (RR, outputColNames etc.) were inconsistent at that point, which you needed to fix?

> PTFOperator does not explain anything in explain statement, making it hard to understand the internal works.
