Subject [jira] [Commented] (HDFS-3255) HA DFS returns wrong token service
Date Thu, 12 Apr 2012 17:25:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13252621#comment-13252621
] 

Daryn Sharp commented on HDFS-3255:
-----------------------------------

I should clarify: It "works" but multiple tokens are fetched for the HA filesystem.  The reason
is the {{TokenCache}} builds a map of tokens keyed on their service.  The value from {{fs.getCanonicalServiceName()}}
is used to check the map for a pre-existing token.  Since the canonical service doesn't match
the value of {{token.getService()}}, it repeatedly fetches a token for a HA filesystem.

> {{fs.getCanonicalService()}} must be equal to {{fs.getDelegationToken(renewer).getService()}}.
 When HA is enabled, the DFS token's service is a logical uri, but {{dfs.getCanonicalService()}}
is only returning the hostname of the logical uri.
