Date Mon, 26 Oct 2015 17:21:27 GMT

    [ https://issues.apache.org/jira/browse/DRILL-3978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14974580#comment-14974580
] 

Jacques Nadeau commented on DRILL-3978:
---------------------------------------

Looks like a problem with the shading in the jdbc-all module. This class is used when returning
maps to the user.

>                 URL: https://issues.apache.org/jira/browse/DRILL-3978
>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Client - JDBC
>    Affects Versions: 1.2.0
>            Reporter: Tomer Shiran

> I was using the JDBC driver and 0xDBE as the client. The query was: 
> {code}
> SELECT * FROM dfs.yelp.`business.json`
> {code}
> Some of the columns resulted in a Java exception string instead of the actual value.
For example, in the hours column:
