Subject [jira] [Commented] (HDFS-10823) Implement HttpFSFileSystem#listStatusIterator
Date Fri, 02 Sep 2016 18:39:21 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10823?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15459264#comment-15459264

Andrew Wang commented on HDFS-10823:

I asked Tucu about this offline, and he told me it's because HttpFS was designed to front
any arbitrary FileSystem (but exposing WebHDFS). I haven't heard of anyone using it except
as an HDFS gateway though, so I think this is an uncommon usecase. There's also an API impedance
mismatch, since WebHDFS was designed for REST access to HDFS, not as a REST API for generic
FileSystem access.

But, without a large overhaul of the HttpFS codebase, I don't think it's something we're going
to address here. I'll try the subclassing hack to at least make the new FileSystem method
protected rather than public. Better alternatives welcomed.
