DRILL-5330: NPE in FunctionImplementationRegistry
Fixes:
* DRILL-5330: NPE in
FunctionImplementationRegistry.functionReplacement()
* DRILL-5331:
NPE in FunctionImplementationRegistry.findDrillFunction() if dynamic
UDFs disabled
For DRILL-5331, we leverage an existing session option to determine if
DUDFs are enabled. If not, we skip the DUDF registry check.
For DRILL-5330, we use an existing option validator rather than
accessing the raw option directly.
Then, both options cached on setup rather than repeatedly resolved in
each function lookup.
Also includes a bit of code cleanup in the class in question.
The result is that the code now works when used in a sub-operator unit
test.
