Jarek Jarcec Cecho resolved SQOOP-2011.
---------------------------------------
Resolution: Not A Problem
We store column list as a {{List}} in the current code and we're providing
complimentary conversion to {{Array}} if/when needed by whoever is calling our
APIs.
> Schema should expose columns in array or list and not both

> Key: SQOOP-2011

> Issue Type: Sub-task
> Reporter: Veena Basavaraj
> Fix For: 2.0.0
>
>
> it is asking for trouble to store the schema columns in array and expose a
> list. the matching code currently uses LIST and it can completely use the
> array and work with it. In all places in IDF code we use the column array via
> the index.
> Array is preferred since it is easier to walk thorugh the object array
> format, there is one-one correspondence between the two with indexes

> Please read the UPDATE section in the above link:) We really do not need the
> abilities of a list, we know the only reason we will use schema columns is
> read only.
