Subject [jira] [Created] (HDDS-324) Use pipeline name as Ratis groupID to allow datanode to report pipeline info

--------------------------------------

             Summary: Use pipeline name as Ratis groupID to allow datanode to report pipeline
info
                 Key: HDDS-324
                 URL: https://issues.apache.org/jira/browse/HDDS-324
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: Ozone Datanode
    Affects Versions: 0.2.1
            Reporter: Mukul Kumar Singh
            Assignee: Mukul Kumar Singh
             Fix For: 0.2.1


Currently Ozone creates a random pipeline id for every pipeline where a pipeline consist of
3 nodes in a ratis ring. Ratis on the other hand uses the notion of RaftGroupID which is a
unique id for the nodes in a ratis ring. 

When a datanode sends information to SCM, the pipeline for the node is currently identified
using dn2PipelineMap. With correct use of RaftGroupID, we can eliminate the use of dn2PipelineMap.
