Sanjay Radia commented on HADOOP-6900:
--------------------------------------
>I do not want to introduce an incompatible change for now.
I don't understand the compatibility argument since this is new API.
We could add a parameter to indicate whether or not continue if a change in the
sub-tree has occurred.
I can live with that as long as folks not interpret it to mean that the list
returned is atomic - if a subdir's content has been
returned then the iterator will not detect it.
Hairong's patch can go though as Suresh has suggested and we can file another
one to finalize this API.

> 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.
