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>
java.lang.NoClassDefFoundError: Could not initialize class
