> Presently SPS is not handling a case where the failed to choose target node 
> for the required storage type. In general, there are two cases:
> # For the given path, unable to find any target node for any of its blocks or 
> block locations(src nodes). Means, no block movement will be scheduled 
> against this path.
> # For the given path, there are few target nodes available for few block 
> locations(source nodes). Means, some of the blocks or block locations(src 
> nodes) under the given path will be scheduled for block movement.
