[jira] [Commented] (LENS-154) Registration of predict udf in remote hive server not working

    [ https://issues.apache.org/jira/browse/LENS-154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14256813#comment-14256813 ] 

Jaideep Dhok commented on LENS-154:
-----------------------------------

One issue is that Hive megastore client does not have an easy to use API to register permanent function when compared with APIs used to create temp function.

Another issue with permanent function is that they have to be created for each 'database'. All dependent jars need to be uploaded to HDFS and readable by all users.

> Instead of registering lazily, we should look to register a permanent function predict during ML initialization.
