    Description

      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.
