---------------------------------
Summary: Handle ContainerReports in the SCM
Key: HDDS-245
URL: https://issues.apache.org/jira/browse/HDDS-245
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: SCM
Reporter: Elek, Marton
Assignee: Elek, Marton
Fix For: 0.2.1
HDDS-242 provides a new class ContainerReportHandler which could handle the
ContainerReports from the SCMHeartbeatDispatchere.
HDDS-228 introduces a new map to store the container -> datanode[] mapping
HDDS-199 implements the ReplicationManager which could send commands to the
datanodes to copy the datanode.
To wire all these components, we need to put implementation to the
ContainerReportHandler (created in HDDS-242).
The ContainerReportHandler should process the new ContainerReportForDatanode
events, update the containerStateMap and node2ContainerMap and calculate the
missing/duplicate containers and send the ReplicateCommand to the
ReplicateManager.
