Re: Automatically REGISTER jars

[Alan Gates]

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.

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,

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.

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,

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
