Scenario is as follows:
a. 2 nodes are available in the cluster (node1 with label "x", node2 with label "y")
b. Submit an application to node1 for label "x".
c. Change node1 label to "y" by using replaceLabelsOnNode command.
d. Verify Scheduler UI for metrics such as "Used Capacity", "Absolute Capacity" etc. "x" still shows some capacity.
e. Change node1 label back to "x" and verify UI and REST o/p
1. "Used Capacity", "Absolute Capacity" etc are not decremented once labels is changed for a node.
2. UI tab for respective label shows wrong GREEN color in these cases.
3. REST o/p is wrong for each label after executing above scenario.
Attaching screen shots also. This ticket will try to cover UI and REST o/p fix when label is changed runtime.
