[jira] [Commented] (HDFS-9051) webhdfs should support recursive list

    [ https://issues.apache.org/jira/browse/HDFS-9051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14744510#comment-14744510 ] 

Colin Patrick McCabe commented on HDFS-9051:
--------------------------------------------

I think it's problematic to move more processing to the NameNode, given that it is a bottleneck for scalability currently.  I don't see why this can't be implemented more effectively on the client.

> There currently doesn't appear to be a way to recursive list a directory via webhdfs without making an individual liststatus call per dir.
