[jira] [Commented] (ORC-1413) ORC row level filter throws Exception
[ https://issues.apache.org/jira/browse/ORC-1413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17716050#comment-17716050 ]
Pavan Lanka commented on ORC-1413:
----------------------------------
[~zratkai] Thanks for raising this.
Is it is possible for you to share the complete stack trace. It is possible that what you gave is missing the actual cause. If possible please share the schema of the ORC files involved here. I guess the LongColumnVector is coming to play because of `'transactional'='true'` even though the schema includes a single text field.
