Dmitriy V. Ryaboy commented on PIG-2525:
----------------------------------------
Why -j? I was thinking we could use properties for that:
pig -Dpig.progress.listener=com.foo.PigListenerImpl
-Dpig.progress.listener.args="foo,bar" -f my_script.pig
> Support pluggable PigProcessNotifcationListeners on the command line

> It would be convenient to be able to implement
> {{PigProcessNotifcationListener}} and to wire it into a pig script. This jira
> is to support setting a listener and its constructor args on the command,
> perhaps like this:
> {{noformat}}
> pig -j MyListener -J "foo,bar,bat" -f my_script.pig
> {{noformat}}
> where {{MyListener}} takes a single string in the constructor which will get
> passed {{foo,bar,bat}}.
