Raghotham Murthy commented on HIVE-771:
---------------------------------------
Do you really need the maps of class to type? You can probably just remove the
following:
In Operator.java:
+ Map<Class<?>, Integer> operatorTypes;
In QueryPlan.java:
+ private static Map<Class<?>, Integer> stageTypes;
+ private static Map<Class<?>, Integer> operatorTypes;
> QueryPlan getStageType and getOperatorType should use a hash map instead of
> the big if
