Subject [jira] [Commented] (HDFS-10823) Implement HttpFSFileSystem#listStatusIterator
Date Wed, 31 Aug 2016 23:40:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15453738#comment-15453738
] 

Andrew Wang commented on HDFS-10823:
------------------------------------

Looking at the HttpFS code, it's a bit tricky to do this. HttpFS uses the FileSystem interface,
which doesn't have an appropriate listStatus method for implementing a cursor. So, we need
an API like the one HDFS-9366 added to FileSystem, and then overriding implementations in
the FileSystem subclasses we care about.

[~xiaochen] any thoughts here? This is turning out to be more work than I expected.
