parameterized type issues
URL: https://github.com/apache/drill/pull/1923#issuecomment-565177247
All that said, hat's off to the folks who did this code. There is an
incredible amount of complex functionality in the metadata & Parquet filter
push down modules! We just need a bit of tweaking to the very fiddly problem of
handling types both statically and dynamically.

> Short-term fixes for metadata API parameterized type issues
> -----------------------------------------------------------
>
> Key: DRILL-7479
> URL: https://issues.apache.org/jira/browse/DRILL-7479
> Project: Apache Drill
> Issue Type: Task
> Affects Versions: 1.17.0
> Reporter: Paul Rogers
> Assignee: Paul Rogers
> Priority: Blocker
> Labels: ready-to-commit
> Fix For: 1.17.0
>
>
> See DRILL-7480 for a discussion of the issues with how we currently use
> parameterized types in the metadata API.
> This ticket is for short-term fixes that convert unsafe generic types of the
> form {{StatisticsHolder}} to the form {{StatisticsHolder<?>}} so that the
> compiler does not complain with many warnings (and a few Eclipse-only errors.)
> The topic should be revisited later in the context of DRILL-7480.
