[jira] [Updated] (HIVE-17689) XPath support for namespaces

     [ https://issues.apache.org/jira/browse/HIVE-17689?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lubos Kulic updated HIVE-17689:
-------------------------------
    Description: 
Issue HIVE-1027 added UDF for XPath queries. Hoever, it does not support setting namespaces (as mentioned in [this|https://issues.apache.org/jira/browse/HIVE-1027?focusedCommentId=12797520&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12797520] comment).

Unfortunatelly, for real world xml data, it is quite hard to use the feature without the namespaces. The underlying Java API supports the namespaces, so it should be quite easy - just to allow some additional parameter for namespace setting. This is how a similar function on Oracle is working.
