Tsz Wo Nicholas Sze commented on HDDS-699: ------------------------------------------ > ... I think it's a trade off between performance and accurancy. Using a > single RW-lock at network topology level has better accurancy while lower > performance. The question is whether accurancy can be sacrified in some cases > without big impact to other modules. That's good point! It is perfectly fine if we provide a high performance but sometime inaccurate API. In such case, we should specify the behavior carefully. > Detect Ozone Network topology > ----------------------------- > > Key: HDDS-699 > URL: https://issues.apache.org/jira/browse/HDDS-699 > Project: Hadoop Distributed Data Store > Issue Type: Sub-task > Reporter: Xiaoyu Yao > Assignee: Sammi Chen > Priority: Major > Attachments: HDDS-699.00.patch, HDDS-699.01.patch, HDDS-699.02.patch > > > Traditionally this has been implemented in Hadoop via script or customizable > java class.
