---------------------------------------

Yes, I can not change HDFS in common but have to do it in HDFS-202. This is 
side effect of having fs in common. :(

> FileSystem#listLocatedStatus should not throw generic RuntimeException to 
> indicate error conditions

> HDFS-6870 introduced FileSystem#listLocatedStatus(), that returns an Iterator 
> to iterate through LocatedFileStatus for files under a directory or 
> recursively under a sub-directory. Iterator currently throws generic 
> RuntimeException to indicate error conditions. API needs to be changed to 
> throw appropriate exceptions to indicate error conditions.
