Summary: Check global replication state of the repored 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
Fix For: 0.2.1
Current container replication handler compare the reported containers with the
previous report. It handles over an under replicated state.
But there is no logic to check the cluster-wide replication count. If a node is
went down it won't be detected.
For the sake of simplicity I would add this check to the ContainerReportHandler
(as of now). So all the reported container should have enough replicas.
We can check the performance implication with genesis, but as a first
implementation I think it could be good enough.
