Li Cheng commented on HDDS-2116: -------------------------------- [~swagle] I think for now the role is taken by PipelinePlacementPolicy, which is instantiated with config as well. It retrieves viable datanodes from NodeManager and apply complex filter rules, which seems quite alike what AllocationManager should do. > Create SCMPipelineAllocationManager 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 > Priority: Major > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
