> External sort does not support "obscure" numeric types
> ------------------------------------------------------
>
> Key: DRILL-5329
> URL: https://issues.apache.org/jira/browse/DRILL-5329
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.10.0
> Reporter: Paul Rogers
>
> A unit test was created to exercise the "Sorter" mechanism within the
> External Sort, which is used to sort each incoming batch. The sorter was
> tested with each Drill data type.
> The following types fail:
> * TinyInt
> * UInt1
> The failure manifests on one of two ways:
> * If dynamic UDFs are enabled, the query crashes with an NPE. (See
> DRILL-5331.)
> * If dynamic UDFs are disabled, the generated code silently skips the
> comparison step, resulting in the sort not actually being done:
> Sorting a set of 20-pseudo-random rows produces the following output:
> {code}
> #, row #, key, value
> 0(0): 11, "0"
> 1(1): 14, "1"
> 2(2): 17, "2"
> 3(3): 0, "3"
> {code}
> The first number is the row index, the second is the row pointed to by the
> sv2 (which should be written to create sort order). Sort was done ASC,
> NULLS_HIGH, by the key field.
> A strong concern here is that there is no error or other warning to the user
> that Drill cannot sort this type; Drill just silently declines to perform the
> operation.
