Subject Re: Container Launching
Date Tue, 10 Jan 2012 05:29:31 GMT
Thanks that has been solved.
Now the problem is
Is there a way to specify
node1: 10 conatiners
node2: 10 containers
Can we specify this kind of list using the application master????
How to specify setHostName("client")
Is there specific format.
