Subject [jira] Updated: (HDFS-592) Allow client to get a new generation stamp from NameNode
Date Tue, 15 Sep 2009 23:43:57 GMT

     [ https://issues.apache.org/jira/browse/HDFS-592?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Hairong Kuang updated HDFS-592:

    Attachment: newGS2.patch

This patch incorporates Kan's reveiw comments and adds a unit test for the new API in ClientProtocol.

I understand your concern about the naming of the API and what you said makes good sense.
But still I do not like the name "pipelineRecovery" or "recoverPipeline". This patch uses
the name "getNewStampForPipeline". If you still do not like the name, could we resolve the
naming issue later? I will keep this in my mind.
