Description

Drill allows the following ways for providing table schema:

• providing schema with table function:
  • specifying inline schema;
  • specifying path to the schema file;
• using schema file in table root directory;
• using schema from Drill Metastore.

But for the case of several schema sources, it wouldn't be specified, whose schema was used.
The goal of this Jira is to either log or specify in query profile the source of the schema.
