`onSchemaChange()` may perhaps be the wrong name. It is why this
functionality is called in this case. But, the actual functionality is closer
to `setupTransfers()` (assuming the removed code was simply moved into the
container class...)

> Drill Query Failing when selecting all columns from a Complex Nested Data
> File (Parquet) Set). There are differences in Schema among the files:
> * The Parquet files exhibit differences both at the first level and within
> nested data types
> * A select * will not cause an exception but using a limit clause will
> * Note also this issue seems to happen only when multiple Drillbit minor
> fragments are involved (concurrency higher than one)
