Subject Re: Is there any way to retrieve table metadata using select rather than show?
Date Fri, 07 Apr 2017 06:06:10 GMT
That's a great idea! We have a label for JIRAs suited to newcomers that
want to experience the contribution process with a simple change.

https://issues.apache.org/jira/browse/IMPALA-5146?jql=project%20%3D%20IMPALA%20AND%20labels%20%3D%20newbie

Feel free to reach out if you need help.
