Review comment:
Went through the code where `selectRel` gets its value and I found that
it can not be null:
If is coming from `internalGenSelectLogicalPlan` which can create it with
the following way
```
outputRel = genUDTFPlan(genericUDTF, genericUDTFName, udtfTableAlias,
udtfColAliases, qb,
...
RelNode udtf = HiveTableFunctionScan.create(cluster, traitSet, list,
rexNode, null, retType,
null);
outputRel = genSelectRelNode(columnList, outputRR, srcRel);
...
HiveRelNode selRel = HiveProject.create(
outputRel = new HiveAggregate(cluster,
cluster.traitSetOf(HiveRelNode.CONVENTION),
```
