[jira] [Updated] (YARN-3409) Add constraint node labels
[ https://issues.apache.org/jira/browse/YARN-3409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Wangda Tan updated YARN-3409:
-----------------------------
Description:
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 group of entities (like teams, departments, etc.). Partitions of a cluster has following characteristics:
- Cluster divided to several disjoint sub clusters.
- ACL/priority can apply on partition (Only market team / marke team has priority to use the partition).
- Percentage of capacities can apply on partition (Market team has 40% minimum capacity and Dev team has 60% of minimum capacity of the partition).
Constraints are orthogonal to partition, they’re describing attributes of node’s 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 >= 2.20 && JDK.version >= 8u20 && x86_64).

- One node can only belong to one partition.
- One resource request can only ask for one partition
