Review Comment:
I met a npe when I make unitest in
`List<SlotDescriptor> slots =
analyzer.getDescTbl().getTupleDesc(tupleId).getSlots();`
because analyzer.getDescTbl().getTupleDesc(tupleId) return null...
so I add this, maybe it is not important , and it should not fix in this
pr. I will delete this.
