Subject [jira] [Commented] (DRILL-2482) JDBC : calling getObject when the actual column type is 'NVARCHAR' results in NoClassDefFoundError
Date Tue, 17 Mar 2015 20:13:38 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14365965#comment-14365965
] 

Rahul Challapalli commented on DRILL-2482:
------------------------------------------

It is of type NVARCHAR.

I did not find the org.apache.hadoop.io.Text class file in the jar. Also there is no 'hadoop'
folder under 'org/apache' itself.
BTW, I am working with the jar file that you provided and not off master
