Chris Douglas commented on YARN-3409:
-------------------------------------
bq. Me and Sunil G tried to delete it but permissions were not there so were
trying to get that done with Jian he and Others and in the mean while you
helped us out. Delete of a branch could not be done by all ?
I don't/shouldn't have any special privileges. Probably a change to the set of
protected branches between when you tried and today.

> 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).
