Fixed in DRILL-7477.
> Allow user to specify table schema in Metastore
> -----------------------------------------------
>
> Key: DRILL-7610
> URL: https://issues.apache.org/jira/browse/DRILL-7610
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.17.0
> Reporter: Paul Rogers
> Assignee: Vova Vysotskyi
> Priority: Major
>
> The Drill Metastore will infer the schema of a table while gathering stats.
> Unfortunately, this creates a chicken-and-egg problem. Some files need the
> Metastore because the schema is ambiguous. Such data won't even scan
> correctly without such information. Classic JSON example:
> {code:json}
> {a: 10} {a: 10.1}
> {code}
> In these cases, the user should first define the table schema, then run the
> {{ANALYZE TABLE}} commands. In such cases, Drill should not attempt to change
> the type information (since the actual data is ambiguous.)
