Hi all,
I am trying to write an application master.Is there a way to specify
node1: 10 conatiners
node2: 10 containers
Can we specify this kind of list using the application master????
Also i set request.setHostName("client"); where client is the hostname of a
node
I checked the log to find the following error
java.io.FileNotFoundException: File
/local1/yarn/.yarn/local/usercache/rahul_2011/appcache/
application_1325760852770_0001 does not exist

i.e containers are only launching within the host where the application
master runs while the other nodes always remain free.
Any ideas.....
