[jira] [Commented] (DRILL-2482) JDBC : calling getObject when the actual column type is 'NVARCHAR' results in NoClassDefFoundError

["Daniel Barclay (Drill) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-2482?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14365919#comment-14365919 ] 

Daniel Barclay (Drill) commented on DRILL-2482:
-----------------------------------------------

That's weird--I've seen org.apache.hadoop.io.Text objects in tracing proxy output (so the class was found and loaded in that case).

Can you check whether that class--or one with a name ending like that but starting with a different, probably added, package--exists in the Drill Jar file you're using?


Also, is the type NVARCHAR (per your title) or VARCHAR (per your description)?
(Or:  Where does it seem to be NVARCHAR() and where does it seem to be VARCHAR? (I've got a pending patch for an "NVARCHAR" that should be "VARCHAR".))
