Mona Chitnis commented on PIG-3866:
-----------------------------------

Why the need to run multiple requests in same JVM - wont that hit memory 
limitations?

> Create ThreadLocal classloader per PigContext

> For shared Hadoop environment, where there are large number of customers who 
> submit PIG jobs for execution, it becomes very cumbersome to handle all 
> support issue (ex providing access to CLI machine to every user, limiting 
> user for submission etc).
> There is need to provide REST based interface for submitting PIG job/view PIG 
> job status/view PIG request output, so that there is single entry point to 
> cluster. With this, users are abstracted of Hadoop configuration and need to 
> get access on machine. Also given it is hosted service, it is possible to 
> provide rate limiting, QoS etc to user.
> We have designed such PIG self-service which provide REST APIs for all 
> operations and this webapp runs under web container. In order to run multiple 
> requests in same JVM, we need to create classloader per request thread.
