Subject [jira] [Created] (DRILL-3978) Exceptions when using JDBC driver
Date Mon, 26 Oct 2015 17:19:27 GMT
Tomer Shiran created DRILL-3978:
-----------------------------------

             Summary: Exceptions when using JDBC driver
                 Key: DRILL-3978
                 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:

<failed to load>
