Hi,
I am a freshman here, I had two question for help.
1. In Job Conductor, I can't run job use an independent process. The same problem is in http://www.talendforge.org/forum/viewtopic.php?id=21646 . In the last, vgalopin said Uncheck that option. Yes, it can work, but there comes problem 2. I want to know if there is some way to run job in Job Conductor use independent process.??

2. I use parallel execution in one job. And in it's subjob I use HashOutput and HashInput componets. I found When I use independent process it was ok. but uncheck independent process, HashInput output value is wrong or even Exception.

As I in need to use parallel execution, hash component and Job Conductor. Anyone has the same problem??
