Dumindu Buddhika commented on PHOENIX-1875:
-------------------------------------------
Oh I am sorry I haven't added a proper test case there :) . In that case, since
nRemainingNulls = 0, There will be no byte written to indicate that. So There
will be no increase in the length(as the byte used to write nRemainingNulls in
the original array will be used to write "1" in the resulting array)
I will add that test case and remove the latter one.
> implement ARRAY_PREPEND built in function
