Subject [jira] [Updated] (HDFS-5502) Fix HTTPS support in HsftpFileSystem
Date Sat, 16 Nov 2013 01:08:18 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5502?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jing Zhao updated HDFS-5502:
----------------------------

       Resolution: Fixed
    Fix Version/s: 2.3.0
     Release Note: Fix the https support in HsftpFileSystem. With the change the client now
verifies the server certificate. In particular, client side will verify the Common Name of
the certificate using a strategy specified by the configuration property "hadoop.ssl.hostname.verifier".
     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

I've committed this to trunk and branch-2. We can address further comments in new sub-tasks
of HDFS-5305.

> The current implementation of HsftpFileSystem suffers from the following issues:
> * It initializes the SSLContext incorrectly. It blindly trusts all server certificates
which creates a security hole.
> * It tries to cancel delegation token through http, not https, which leads to HDFS-5295.
> * It overrides the default socket factory for HttpsConnection. Given the fact that it
trusts all server-side certificate, it accidentally disables all checks on server certificates
for all https connections.
> This jira tracks the effort to fix the above issues.
