Subject [jira] [Updated] (YARN-7696) Add container tags to ContainerTokenIdentifier, api.Container and NMContainerStatus to handle all recovery cases
Date Wed, 03 Jan 2018 18:10:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-7696?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arun Suresh updated YARN-7696:
------------------------------
    Description: 
The NM needs to persist the Container tags so that on RM recovery, it is sent back to the
RM via the NMContainerStatus. The RM would then recover the AllocationTagsManager using this
information.
The api.Container also requires the allocationTags since after AM recovery, we need to provide
the AM with previously allocated containers.
