Subject [jira] [Commented] (HDFS-1150) Verify datanodes' identities to clients in secure clusters
Date Wed, 30 Mar 2011 23:11:06 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13013723#comment-13013723
] 

Allen Wittenauer commented on HDFS-1150:
----------------------------------------

Ugh.  We really need to do better documentation on how to build Hadoop, esp wrt the security
features.  I know I didn't know about the jsvc.location ant param. (But then again, I don't
build as often as most of you.)

FWIW, we're going to have this problem with all compiled code that doesn't use architecture-aware
naming, even in some cases between 32-bit and 64-bit on Linux, without a lot of work in various
locations.  (Oh how I wish isaexec() and isalist() was on all platforms!)

> 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.
