Naganarasimha G R 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). Attributes are orthogonal to partition, they’re describing features of node’s hardware/software just for affinity. Some example of attributes: - 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). was: 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.).
