http://gerrit.cloudera.org:8080/#/c/4862/1/be/src/exec/kudu-scanner.cc
File be/src/exec/kudu-scanner.cc:

Line 191:     row->SetTuple(tuple_idx(), kudu_tuple);
If we just assume that tuple_idx() is 0, then we can just do something like:

  TupleRow* tmp_row = reinterpret_cast<TupleRow*>(&kudu_tuple);


http://gerrit.cloudera.org:8080/#/c/4862/1/be/src/exec/kudu-scanner.h
File be/src/exec/kudu-scanner.h:

Line 94:   int tuple_idx() const { return 0; }
Not your change but this generality seems wholly unnecessary, I think we can 
simplify other code if we just assume it's 0.

File be/src/runtime/tuple.cc:

Line 83:   DeepCopy(result, desc, pool);
E.g. this is dropping the Status on the floor.


http://gerrit.cloudera.org:8080/#/c/4862/1/be/src/runtime/tuple.h
File be/src/runtime/tuple.h:

Line 95:   Status DeepCopy(Tuple* dst, const TupleDescriptor& desc, MemPool* 
pool);
There are other callsites that need to be fixed to handle the status, aren't 
there?
