Elek, Marton commented on HDDS-400: ----------------------------------- I agree. But the big question is that where can we handle the new nodes. I modified the patch with moving the logic to the DeadNodeHandler. With this approach the 'new node' case is not covered, it should be addressed by a new jira. > Check global replication state of the reported containers on SCM > ---------------------------------------------------------------- > > Key: HDDS-400 > URL: https://issues.apache.org/jira/browse/HDDS-400 > Project: Hadoop Distributed Data Store > Issue Type: Bug > Components: SCM > Reporter: Elek, Marton > Assignee: Elek, Marton > Priority: Blocker > Fix For: 0.2.1 > > Attachments: HDDS-400.001.patch, HDDS-400.002.patch, > HDDS-400.004.patch, HDDS-400.005.patch > > > Current container replication handler compare the reported containers with > the previous report.
