Venki Korukanti updated DRILL-699:
----------------------------------
Description: We maintain a Map<String, DrillFuncHolder> for functions that
map the given function name to holder. Here the function name is added to map
as it is given in FunctionTemplate without any case changes. The problem is
after the Optiq-Drill conversion, all function names are converted to lowercase
(in DrillOptiq.java). So if a function name is "isTrue" in the registry, we
search for "istrue" and don't find any function during materialization. (was:
