Apache Drill - Clear Parquet Metadata Cache?

Keywords:apache  drill 


Is it possible to clear the parquet metadata cache in Apache Drill?

I'm finding that when you version files and use maxdir(), it holds on to old versions which may be deleted.

It seems like there should be a "clear metadata cache" command to cancel out the "refresh metadata cache" command.

Unfortunately, there is no such functionality in Drill so far. Please log Jira for improvement [1]. Contributions always welcome.
