[jira] [Created] (HDDS-477) remove NodeManager usage from Pipeline selector

Mukul Kumar Singh created HDDS-477:
--------------------------------------

             Summary: remove NodeManager usage from Pipeline selector
                 Key: HDDS-477
                 URL: https://issues.apache.org/jira/browse/HDDS-477
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: SCM
    Affects Versions: 0.3.0
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh
             Fix For: 0.3.0


With HDDS-476, PipelineSelector also receives heartbeat from the datanodes. Hence there is no need for PipelineSelector to use the NodeManager and its usage can be replaced with Node2PipelineMap. This jira proposes use remove NodeManager from PipelineSelector and also use a min heap based allocator for creating ratis pipelines.
