If we can convince our selves that the performance benefit of this change is great, it will be worth while to spend time to find a way to introduce this without incompatibility. The performance here can be viewed in two angles: 1) impact on name node and 2) decommissioning speed. I will also try to review the patch. I think everyone agrees that we need to improve decommissioning. > Refactor and improve decommissioning logic into DecommissionManager > ------------------------------------------------------------------- > > Key: HDFS-7411 > URL: https://issues.apache.org/jira/browse/HDFS-7411 > Project: Hadoop HDFS > Issue Type: Improvement > Affects Versions: 2.5.1 > Reporter: Andrew Wang > Assignee: Andrew Wang > Attachments: hdfs-7411.001.patch, hdfs-7411.002.patch, hdfs-7411.003.patch, hdfs-7411.004.patch, hdfs-7411.005.patch, hdfs-7411.006.patch, hdfs-7411.007.patch, hdfs-7411.008.patch, hdfs-7411.009.patch, hdfs-7411.010.patch > > > Would be nice to split out decommission logic from DatanodeManager to DecommissionManager. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
