 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.
