Subject [jira] [Updated] (YARN-3223) Resource update during NM graceful decommission
Date Mon, 30 Nov 2015 19:07:11 GMT

     [ https://issues.apache.org/jira/browse/YARN-3223?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brook Zhou updated YARN-3223:
-----------------------------
    Attachment: 0001-YARN-3223-resource-update.patch

Since completedContainer is often called multiple times like from nodeUpdate(), I moved the
trigger of RMNodeResourceUpdateEvent directly into nodeUpdate() when a node is decommissioning.
If this is ok, I will add similar code to Fifo/Fair schedulers.

make RMNode keep track of old resource for possible rollback, keep available resource to 0
and used resource get updated when
> container finished.
