Tsz Wo (Nicholas), SZE commented on HDFS-1547: ---------------------------------------------- {quote} - 10 nodes, each of which has 2 transceivers active (total load = 20) - decommission 6 of them {quote} Hi Todd, this is a good observation but I think we should never decommission 60% of nodes at once. Or the cluster should not be being used with decommissioning 60% of nodes. Just like that we don't expect the cluster is still working fine when many nodes, say > 50%, are down. So I doubt if this is a valid use case. > Improve decommission mechanism > ------------------------------ > > Key: HDFS-1547 > URL: https://issues.apache.org/jira/browse/HDFS-1547 > Project: Hadoop HDFS > Issue Type: Improvement > Components: name-node > Affects Versions: 0.23.0 > Reporter: Suresh Srinivas > Assignee: Suresh Srinivas > Fix For: 0.23.0 > > Attachments: HDFS-1547.1.patch, HDFS-1547.patch > > > Current decommission mechanism driven using exclude file has several issues. > This bug proposes some changes in the mechanism for better manageability.
