Hi Sandy,
Thanks for the reply and it is good to know YARN-521 is done! Please
answer my following questions
1) when is 2.1.0-beta going to be released? is it soon or do you suggest me
take it from the trunk or is there a recent release candidate available?
2) I have recently changed my application to use the new Asynchronous
interfaces. I am hoping it works with that too, correct me if I am wrong.
3) Change in interface:
The old interface for ContainerRequest constructor used to be this:
public ContainerRequest(Resource capability, String[] nodes,
String[] racks, Priority priority, int containerCount);
where as now it is changed to
a) public ContainerRequest(Resource capability, String[] nodes,
String[] racks, Priority priority)
&
b) public ContainerRequest(Resource capability, String[] nodes,
String[] racks, Priority priority, boolean relaxLocality)
that means the old argument containerCount is gone! How would I be able to
specify how many containers do I need?
