Subject [jira] [Commented] (HIVE-13116) LLAP: allow ignoring the UDF check during compile time
Date Wed, 24 Feb 2016 10:40:18 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15162798#comment-15162798
] 

Lefty Leverenz commented on HIVE-13116:
---------------------------------------

Doc note:  This adds *hive.llap.skip.compile.udf.check* to HiveConf.java, so it will need
to be documented in the wiki for the 2.1.0 release, in a new LLAP section of Configuration
Properties (see HIVE-12597).

> Before UDF support is implemented, users can utilize auxjars option to package additional
jars in the LLAP slider package (that was initially intended for serdes) to have some primitive
UDF support. The only obstacle is that the query with UDFs will not be sent to LLAP right
now; the user should be able to override that; the query with UDFs will be sent to LLAP then,
and either work from a pre-packaged jar, or fail if there's no jar for this UDF (there will
be no localization).
> That can also be used later if desired to avoid the permanent UDF route, or for other
special circumstances (like bugs in localization ;)).
