> Currently DFSStripedInputStream assumes we always have complete internal
> block location information, i.e., we can always get all the DataNodes for a
> striped block group. In a lot of scenarios the client cannot get complete
> block location info, e.g., some internal blocks are missing and the NameNode
> has not finished the recovery yet. We should add functionality to handle
> missing block locations in DFSStripedInputStream.
