Subject [jira] Updated: (HDFS-1150) Verify datanodes' identities to clients in secure clusters
Date Wed, 12 May 2010 22:20:42 GMT

     [ https://issues.apache.org/jira/browse/HDFS-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jakob Homan updated HDFS-1150:
------------------------------

    Attachment: HDFS-1150-Y20S-Rough.txt

First, very rough patch against Y20S branch for secure datanode wrapper that uses jsvc/commons
daemon to start up as root and then drop privs.  Still need to modify shell scripts to use
new class, as well as add to build file to compile jsvc (similar to MR's LinuxTaskController).
 Having trouble bringing in commons daemon via ivy...  Not for commit, etc, etc.

> Currently we use block access tokens to allow datanodes to verify clients' identities,
however we don't have a way for clients to verify the authenticity of the datanodes themselves.
