Wangda Tan updated YARN-3409:
-----------------------------
    Description:=20
Specify only one label for each node (IAW, partition a cluster) is a way to=
 determinate how resources of a special set of nodes could be shared by a g=
roup of entities (like teams, departments, etc.). Partitions of a cluster h=
as following characteristics:
- Cluster divided to several disjoint sub clusters.
- ACL/priority can apply on partition (Only market team / marke team has pr=
iority to use the partition).
- Percentage of capacities can apply on partition (Market team has 40% mini=
mum capacity and Dev team has 60% of minimum capacity of the partition).

Constraints are orthogonal to partition, they=E2=80=99re describing attribu=
tes of node=E2=80=99s hardware/software just for affinity. Some example of =
constraints:
- glibc version
- JDK version
- Type of CPU (x86_64/i686)
- Type of OS (windows, linux, etc.)

With this, application can be able to ask for resource has (glibc.version >=
=3D 2.20 && JDK.version >=3D 8u20 && x86_64).
