> {{chooseSourceDatanodes}} returns the {{ProvidedDatanodeDescriptor}} as the source of
Provided blocks. As this isn't a physical datanode and doesn't exist the topology, {{ReplicationWork.chooseTargets}}
might fail depending on the chosen {{BlockPlacementPolicy}} implementation. This JIRA aims
to fix this issue.
