Review comment:
Yes, I did some experiments with map column in avro and figured out that
Drill detected MAP type exactly same as for binary table. And bug DRILL-6944
was reproduced for view created over avro file before I made the fix (this fact
mentioned in Jira also). So I think we can rely on added tests to ensure that
issue is gone.
