Subject [jira] Commented: (HDFS-592) Allow client to get a new generation stamp from NameNode
Date Mon, 14 Sep 2009 19:10:57 GMT

    [ https://issues.apache.org/jira/browse/HDFS-592?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12755136#action_12755136

Hairong Kuang commented on HDFS-592:
------------------------------------

> the client can use pipelineRecovery() call to get an access token since it already holds
the lease. 
My main point is that I still want to keep the method name as it is in the patch or a short
form like getNewStampAndToken(). Getting a new GS and access token is just one small step
towards pipeline setup/recovery. The name pipelineRecovery() is too vague.
