[jira] [Comment Edited] (YARN-6597) Store and update allocation
tags in the Placement Constraint Manager
[ https://issues.apache.org/jira/browse/YARN-6597?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16301574#comment-16301574 ]

YARN-7522 introduced AllocationTagManager component which is storing simple node to application-container mappings.
YARN-7653 added support for node-group/rack to application-container mappings.
In this JIRA I would like to efficiently manage container tags under all possible Container state transitions (EXPIRED, RELEASED, KILLED e.t.c) as we currently support only container allocation and completion states as a proof of concept.
Does it make sense?

> Each allocation can have a set of allocation tags associated to it.
> For example, an allocation can be marked as hbase, hbase-master, spark, etc.
> These allocation-tags are active in the cluster only while that container is active (from the moment it gets allocated until the moment it finishes its execution).
> This JIRA is responsible for storing and updating in the {{PlacementConstraintManager}} the active allocation tags in the cluster.
