------------------------------------------------------------
[~sunilg], There are actually two aspects to this:
# Supporting node attributes as a Target Expression: For eg: place containers
with allocation tag "foo" on nodes with attribute java_version = 1.8.
# Supporting node attributes as a Scope: For eg: place 5 containers, no more
than one per failure domain. Assuming all nodes in cluster has a node attribute
called "failure_domain" with values 1 - 10.
1) can be tackled here I guess. but 2) needs some modifications to the
AllocationTagsManager and should be handled YARN-7858.
Thoughts [~kkaranasos] / [~leftnoteasy] ?
