Ashutosh Chauhan commented on HIVE-11271:
-----------------------------------------
Plan which is broken at compile time but is patched up at runtime to work
correctly is a *bad* idea because the notion of brokeness is only between this
piece of code and at runtime and is opaque to everything in between. So, any
subsequent code which mutates the plan (e.g, logical optimizer rules or
physical compiler (MR/Tez/Spark compiler)) has to accomodate for this special
condition.
In general, at any time plan should be fully self-describing and not rely on
subsequent patching.
