> In MisReplicationHandler.getTargetDatanodes() the logic tries to get the
> required nodes and if it cannot it tries for less nodes to allow a partial
> recovery.
> If the requested node count does not equal the number returned, it currently
> logs a warning:
> {code}
> if (targetDatanodes.size() < replicasToBeReplicated.size()) {
> LOG.warn("Placement Policy {} found only {} nodes for Container: {}," +
> " number of required nodes: {}, usedNodes : {}",
> containerPlacement.getClass(), targetDatanodes.size(),
> container.getContainerID(), replicasToBeReplicated.size(),
> usedDns);
> }
> {code}
> In such a case, after sending the commands we can, it should thrown an
> exception to it is requeued for retry later, rather than returning
> successfully.
