File be/src/runtime/row-batch-test.cc:

Line 38:   vector<bool> nullable_tuples(1, false);
This is ok, but I find the c++11 initialisers for vectors a bit nicer. e.g. 
nullable_tuples({false})


PS1, Line 39: TTupleId
This should be a static_cast according to our coding standard.


Line 60:     ASSERT_DEBUG_DEATH(bad_dest.AcquireState(&src), "");
> Will change to IMPALA_ASSERT_DEBUG_DEATH when related patch lands.
We should make sure to merge that first, otherwise we will have a lot of core 
dumps.

File be/src/runtime/row-batch.cc:

Line 319:   capacity_ = tuple_ptrs_size_ / (num_tuples_per_row_ * 
sizeof(Tuple*));
We already know the initial capacity using this calculation - we should compute 
it the same way in both places. Maybe just factor this out into an 
InitialCapacity() function?
