[jira] [Commented] (HIVE-3050) JDBC should provide metadata for columns whether a column is a partition column or not

["chandra sekhar gunturi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-3050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13908102#comment-13908102 ] 

chandra sekhar gunturi commented on HIVE-3050:
----------------------------------------------

This is required even for creating load command when hive table is partitioned. When the Hive table is partitioned, load command  should have 'partitioned' clause. To give the load command programatically, depending on metadata, this functionality is useful.
