Subject Re: Ajax library for Pig
Date Tue, 14 Apr 2009 21:32:01 GMT
Hi
Currently I am under one doubt. How this system can be designed so that
multiple users can run same pig.
Current scenario is  - User executes its own copy of pig.jar on shell and
access hadoop.

But under this system multiple users will log-in to some domain and they
have separate sessions. Now suppose user1 submits a pig script or access
pig. Then user2 also access pig shell. How this system will work for
multiple users? I am not sure what can be the optimized solution.
