-------------------------------------
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.
