Phabricator commented on HIVE-3946:
-----------------------------------
njain has commented on the revision "HIVE-3946 [jira] Make it possible to
configure for each stage".
What are the exact semantics ?
If Stage 4 depends on Stage 3, which depends on Stage 2, which depends on
Stage 1.
Say, a parameter 'x' = 10
Say, stage-1.x = 20
What is 'x' for stage-2 (is it supposed to be 10 or 20) ?
