             Summary: Function resolutions fails to find functions in registry during the materialization due to case sensitive issues
                 Key: DRILL-699
                 URL: https://issues.apache.org/jira/browse/DRILL-699
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Venki Korukanti
            Assignee: Venki Korukanti


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. So if a function name is "isTrue" is in registry, we search for "istrue" and don't find any function during materialization.
