Being able to add jars from the command line seems like a useful thing to be able to do. I've created https://issues.apache.org/jira/browse/PIG-1226 to track this.

I would love to be able to register jars when starting the commandline. This is exactly what I need. I think we just need to create a -r switch in Main
that calls pigContext.addJar(). Is this right?

Thanks,
Chris

Alan,

Thanks for the clarification. This thread raises an important issue. I think it would be worthwhile to be able to set up some mechanism for setting up a "script environment." Maybe an option to be able to register jars on the command line or maybe some way of including/requiring dummy scripts (with
register commands) as part of other scripts. Thoughts?

Putting the jars on your classpath works as long as the classes you need
are directly referenced in your script.  So:

B = foreach A generate com.mycompany.myudf($0);

If myudf is in a jar somewhere in your classpath then it will be picked up. If myudf depends on the class myudfsupport which is also in a jar on your classpath, myudfsupport will not be picked up. It must be explicitly
registered.

I've never tried this but putting te jars on your pig classpath should
save you from having to register as I believe pig looks here for jars by
default

What I want to do is register the jar WITHOUT register. That is, when I
issue my pig commandline call to start pig, it will register it at that
point rather than in my pig script.

This will save our users from all having to register 3 or 4 jars that
they
always will need to use pig effectively on our Hadoop cluster.

Thanks,
Chris

Hi All,

We have a use-case where we want to automatically register certain jars
for
command-line users. I tried using –jar, but this switch seems to do
absolutely nothing.

How do we go about auto-registering jars using pig? Any help is much
appreciated.

Thanks in advance!
Chris
