[jira] [Commented] (PHOENIX-2426) Spark Data Source API Giving Exception

["Josh Mahonin (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-2426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15008857#comment-15008857 ] 

Josh Mahonin commented on PHOENIX-2426:
---------------------------------------

Patch attached. The catalyst mapper was missing the SMALLINT data type. It was also missing TINYINT, so I've included that as well.

I think the catalyst matchers are (finally) complete for non-abstract PDataTypes, but if anyone else wants to help double-check for me, the Phoenix types are here [1] and the Spark types are here [2]. The Spark types don't appear to have changed since 1.3
