Subject [jira] Commented: (HIVE-691) show documentation for user defined functions
Date Thu, 30 Jul 2009 20:46:14 GMT

    [ https://issues.apache.org/jira/browse/HIVE-691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12737271#action_12737271

Prasad Chakka commented on HIVE-691:
------------------------------------

i think the brief description not that much useful without the arguments. It should atleast
contain the arguments and the extended can contain detailed description and also example if
needed.

> show documentation for user defined functions

> There are lot of functions and more of them will be added. I think it is cumbersome to
update wiki or ask users to go to wiki to find out documentation. instead each user defined
function can have an annotation containing documentation and 'show functions' command or similar
can show the documentation to users on command line. it will also be easier to update the
documentation along with code.
