Subject [jira] Commented: (HIVE-580) command to list available UDF names
Date Mon, 27 Jul 2009 22:04:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-580?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12735802#action_12735802

Namit Jain commented on HIVE-580:
---------------------------------

Since, mFunctions in FunctionRegistry is a hashmap - it does not guarantee any order.
So, output of show functions is non-deterministic.

Please change mFuntions to a linkedhashmap.

Otherwise, the changes look good.

> It would be great if there was some way to list all available UDF names in the CLI.
> Ideally, there would be some way for the UDFs themselves to provide a description/help
that could also be displayed.
> Would also be nice if the UDF names were available for auto-completion (HIVE-97).
> As a start, just having the names available would be great.
