nijel commented on YARN-3018:
-----------------------------
The test failure can be solved by changing the following lines in
TestLeafQueue.testLocalityConstraints()
- verify(app_0,never()).allocate(eq(NodeType.RACK_LOCAL), eq(node_1_1), -
line number 2394
+ verify(app_0, never()).allocate(eq(NodeType.NODE_LOCAL), eq(node_1_1),
any(Priority.class), any(ResourceRequest.class), any(Container.class));
assertEquals(0, app_0.getSchedulingOpportunities(priority));
- assertEquals(1, app_0.getTotalRequiredResources(priority)); - line
number 2397
+ assertEquals(0, app_0.getTotalRequiredResources(priority));
But i am not sure about the impact. Can any one help me in this ?

> For the configuration item "yarn.scheduler.capacity.node-locality-delay" the
> default value given in code is "-1"
> public static final int DEFAULT_NODE_LOCALITY_DELAY = -1;
> In the default capacity-scheduler.xml file in the resource manager config
> directory it is 40.
> Can it be unified to avoid confusion when the user creates the file without
> this configuration. IF he expects the values in the file to be default
> values, then it will be wrong.
