> # Extraneous INFO logging in VectorReduceSinkCommonOperator
> # NPE in EXPLAIN for some SelectColumnIsTrue vector expressions
> # Don't throw instantiation exception when UDF has NULL SCALAR that cannot
> match vectorization expression description. Catch it early and don't try to
> create vectorization expression for UDF. (try VectorUDFAdaptor instead).
> # Support vectorizing SELECT NULL.
> # Support constant casting from \{STRING|CHAR|VARCHAR} to
> \{LONG|DOUBLE|DECIMAL} case.
> # Suppress fatal Vectorizer exceptions. Put single line exception stack
> trace innotVectorizedReason. Add test only variable
> hive.test.vectorizer.suppress.fatal.exceptions to turn that off so Vectorizer
> execution failure can be found more easily.
