Subject [jira] [Updated] (HDDS-561) Move Node2ContainerMap and Node2PipelineMap to NodeManager
Date Sun, 30 Sep 2018 18:31:00 GMT

     [ https://issues.apache.org/jira/browse/HDDS-561?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nanda kumar updated HDDS-561:
-----------------------------
    Description: As {{NodeManager}}/{{SCMNodeManager}} is the one who handles the lifecycle
and also the one who maintains the current state of a node/datanode in SCM, {{Node2ContainerMap}}
and {{Node2PipelineMap}} should be maintained by {{NodeManager}}. Other components in SCM
should query {{NodeManager}} to get this info. It will make the code look cleaner and easy
to maintain.
