[jira] [Commented] (HADOOP-5732) SFTP FileSystem

    [ https://issues.apache.org/jira/browse/HADOOP-5732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162145#comment-13162145 ] 

Wolfgang Nagele commented on HADOOP-5732:
-----------------------------------------

I have put together an implementation that is using Ganymed SSH as library. The main advantage is that this library has a way better performance in SFTP transfers because it runs multiple data fetches in parallel (specifically noticeable on high latency connections). It's on Github: https://github.com/wnagele/hadoop-filesystem-sftp

> I have implemented a FileSystem that supports SFTP. It uses JSch (http://www.jcraft.com/jsch/) in order to manage SFTP.
