Query on ContainerRequest

Does ContainerRequest guarantees containers allocated asked on specific
nodes ?

 public ContainerRequest(Resource capability, String[] nodes,
        String[] racks, Priority priority, int containerCount)

Hi Kapoor,

Blacklisting as described in YARN-398 is not the preferred way to
accomplish this.  You should use the ContainerRequest constructor that has
a relaxLocality paramater, and set it to false.  This was introduced in
YARN-521, and will be included in 2.1.0-beta.

It provides more control for whitelisting/blacklisting of resources for your application. You need to send the requests to RM on those specific nodes and blacklist ANY. 

Thanks

Thanks for the jira link Devraj.

Just curious, If i want to run my application on dictated nodes then, I have to blacklist rest of the nodes which I don't want for the application ?

Thanks for the jira link Devraj.

Just curious, If i want to run my application on dictated nodes then, I
have to blacklist rest of the nodes which I don't want for the application ?
