Subject [jira] Commented: (PIG-1354) UDFs for dynamic invocation of simple Java methods
Date Fri, 16 Apr 2010 19:20:30 GMT

    [ https://issues.apache.org/jira/browse/PIG-1354?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12857943#action_12857943

Dmitriy V. Ryaboy commented on PIG-1354:
----------------------------------------

Ashutosh, nice brainstorm, but I  think that if you are to the point of actually writing java,
you should write java. In a proper IDE. With highlighting, intellisense, javadoc lookup, and
all those other awesome bells and whistles.  Plus, reusable code and all that.

To Alan's earlier point -- I think it would be valuable to allow bags (transformed into arrays)
as arguments. That opens up a large set of statistical functions from Apache Commons, for
example.  Wouldn't work for giant bags that don't fit into memory, but nice for smaller groups.

> The need to create wrapper UDFs for simple Java functions creates unnecessary work for
Pig users, slows down the development process, and produces a lot of trivial classes. We can
use Java's reflection to allow invoking a number of methods on the fly, dynamically, by creating
a generic UDF to accomplish this.
