[jira] Created: (HIVE-580) command to list available UDF names
command to list available UDF names
-----------------------------------
Key: HIVE-580
URL: https://issues.apache.org/jira/browse/HIVE-580
Project: Hadoop Hive
Issue Type: New Feature
Components: Clients, Documentation
Reporter: Larry Ogrodnek
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.

[jira] Updated: (HIVE-580) command to list available UDF names
Posted by "Scott Chen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HIVE-580?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Scott Chen updated HIVE-580:
----------------------------
Attachment: hive-580-2009-07-25.patch
"SHOW FUNCTIONS;" will list all the udf.
"SHOW FUNCTIONS 'regular expression string';" will list all the udf matches the regular expression.
Most of the logic in this patch follows "SHOW TABLE".

---------------------------------
Also, can you add some property which shows the signature and the properties of the function (whether it is temporary or not).
You can add something like:
describe function {extended}
You can also do the describe in a follow-up - in that case please file a JIRA for the same

Attachment: hive-580-2009-07-26.patch
@Yongqing: Thanks. I have checked with the convention but I only changed few things. It would be good if you can point out the file and lineno.
@Namit: That is a very good suggestion. But as Zheng mentioned there's hive-691 on this one.
@Zheng: Thanks for the comments. I have add javadoc to 3 new functions that I added. And LOG.info has been changed to LOG.warn in both showFunctions and showTables.

That's a good idea.
It should be pretty easy to do since FunctionRegistry has all the information needed.

That's good. We should avoid adding all command processing logics in one CliDriver. I can see CliDriver will get fatter and fatter as new commands got in.

------------------------------------
One question about this patch. This does not print out UDAFs - granted that we do not yet have the capability to register UDAFs but I think it would be good to be able to list out UDAFs as well considering that we are adding new ones soon. Also show_functions.q.out does not seem to be part of the patch.

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.

---------------------------------
Yes, it would be better to add a 'show functions' command supported by the hive parser itself.

Zheng Shao commented on HIVE-580:
---------------------------------
Overall the patch looks pretty good. Some nitpicks:
@hive-580-2009-07-25.patch:
43,47: Can you add javadoc for all new functions? I know we don't have javadoc for all functions, but a while back we've decided to add "javadoc" for all new functions (and gradually do that for all old functions as well).
141: LOG.warn instead of LOG.info. (Can you do the same change to showTables?)

------------------------------------
@yongqing, we are trying to move away from processing queries inside CliDriver.java. This just creates problems later on. Joydeep is planning to move all such commands/constructs (set, add, comments) from CliDriver into parser. I don't think we should add this command here.
