> 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)
