[jira] [Created] (HDDS-2116) Create SCMAllocationManager as background thread for pipeline creation

Li Cheng created HDDS-2116:
------------------------------

             Summary: Create SCMAllocationManager as background thread for pipeline creation
                 Key: HDDS-2116
                 URL: https://issues.apache.org/jira/browse/HDDS-2116
             Project: Hadoop Distributed Data Store
          Issue Type: Sub-task
            Reporter: Li Cheng


SCMAllocationManager can be leveraged to get a candidate set of datanodes based on placement policies. And it should make the pipeline creation process to be async and multi-thread. This should be done when we encounter with performance bottleneck in terms of pipeline creation.
