Subject [jira] Updated: (HADOOP-5732) SFTP FileSystem
Date Wed, 09 Sep 2009 10:19:57 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-5732?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Tom White updated HADOOP-5732:
------------------------------

    Attachment: HADOOP-5732.patch

I've updated the patch so that applies to trunk. As it stands the unit test isn't self-contained.
Can this be done by having an embedded SFTP server like TestFTPFileSystem does? (Although
see https://issues.apache.org/jira/browse/HDFS-441.)

If this is not possible then the test should be renamed SFTPFileSystemTest so it isn't run
as a part of the automated test suite.

Ideally, the FileSystem interface contract should also be tested by subclassing FileSystemContractBaseTest
and overriding the setUp() method to set the filesystem under test to be SFTPFileSystem. See
TestHDFSFileSystemContract in the HDFS project for an example of how to do this. This test
checks lots of edge cases and will help flush out common issues with writing FileSystem implementations.

> should I add a modification in hadoop-default.xml in order to add fs.impl.sftp value?

Yes please.

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