Subject [jira] Commented: (PIG-602) Pass global configurations to UDF
Date Tue, 10 Feb 2009 19:57:59 GMT

    [ https://issues.apache.org/jira/browse/PIG-602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12672377#action_12672377

Olga Natkovich commented on PIG-602:

Alan, looks good.

The only thing I would propose to change is to handle information on the client side as Java
properties. This means

(1) That individual properties can be passed via -D switch from the command file 
(2) .properties files passed by users will get picked up. (Not sure exactly what Java's mechanism
for this is.)

> We are seeking an easy way to pass a large number of global configurations to UDFs.
> Since our application contains many pig jobs, and has a large number of configurations.
Passing configurations through command line is not an ideal way (i.e. modifying single parameter
needs to change multiple command lines). And to put everything into the hadoop conf is not
an ideal way either.
> We would like to see if Pig can provide such a facility that allows us to pass a configuration
file in some format(XML?) and then make it available through out all the UDFs.
