[jira] [Updated] (YARN-7522) Add application tags manager implementation

["Wangda Tan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-7522?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Wangda Tan updated YARN-7522:
-----------------------------
    Attachment: YARN-7522.YARN-6592.wip-001.patch

Attached wip implementation which included tracking and look up cardinality by app/container-tag for given node. 

I can add reverse look up (get list of nodes by given criteria), but I'm not sure which one is the immediate item which required by LP-solver implementation. For a simple affinity/anti-affinity implementation, look up cardinality by app/container-tag for given node should be enough.

[~kkaranasos]/[~asuresh]/[~sunilg], any suggestions here?

> This is different from YARN-6596, YARN-6596 is targeted to add constraint manager to store intra/inter application placement constraints. This JIRA is targeted to support storing maps between container-tags/applications and nodes. This will be required by affinity/anti-affinity implementation and cardinality.
