Steve Loughran commented on HADOOP-17281:
-----------------------------------------

looking forward to this. Needs a followup across our internal code to make sure 
that this is used when we list -benefits large HDFS directory listings too. In 
those situation, I think we should also call close() at the end if they are 
closeable. We should set an example for all

Once HADOOP-16830 is in, it will be easier to iterate

> Implement FileSystem.listStatusIterator() in S3AFileSystem

> Currently S3AFileSystem only implements listStatus() api which returns an 
> array. Once we implement the listStatusIterator(), clients can benefit from 
> the async listing done recently 
> https://issues.apache.org/jira/browse/HADOOP-17074  by performing some tasks 
> on files while iterating them.
