> I recently wrote a UDF which emits BINARY values (as implemented in
> [HIVE-2380|https://issues.apache.org/jira/browse/HIVE-2380]). When testing
> this, I encountered the following exception (because I was evaluating
> f(g(constant string))) and g() was emitting a BytesWritable type.
> FAILED: Hive Internal Error: java.lang.RuntimeException(Internal error:
> Cannot find ConstantObjectInspector for BINARY)
> java.lang.RuntimeException: Internal error: Cannot find
> ConstantObjectInspector for BINARY
