Subject [jira] [Commented] (HDFS-2854) SecurityUtil.buildTokenService returns java.net.UnknownHostException when using paths like viewfs://default/some/path
Date Thu, 02 Feb 2012 22:56:54 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13199327#comment-13199327
] 

Daryn Sharp commented on HDFS-2854:
-----------------------------------

The main problem is the {{TokenCache}}.  It assumes that a uri's authority is its token's
service type, and tries to look that service up in its {{Credentials}} cache.  The authority
for {{ViewFileSystem}} has nothing to do with its token service, in fact, it has multiple
tokens.  It's fundamentally broken and will be fixed on HADOOP-7967.
