I've made a little change in `TransformOperandFactory`, putting the 'IN' and
'NOT_IN' operator in the case expression:
````
private static TransformOperand
getTransformOperand(RexExpression.FunctionCall functionCall, DataSchema
dataSchema) {
List<RexExpression> operands = functionCall.getFunctionOperands();
int numOperands = operands.size();
String canonicalName =
OperatorUtils.canonicalizeFunctionName(functionCall.getFunctionName());
switch (canonicalName) {
case "IN":
Preconditions.checkState(numOperands >= 2, "IN takes >=2 arguments,
got: %s", numOperands);
return new FilterOperand.In(operands, dataSchema, false);
case "NOT_IN":
Preconditions.checkState(numOperands >= 2, "NOT_IN takes >=2
arguments, got: %s", numOperands);
return new FilterOperand.In(operands, dataSchema, true);
case "AND":
.....
````
And I've implemented the `In` class, the engine starts working well. I'm not
sure, this is the good solution, but it seems to be a fix.
