[ 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.

ClientName should never be null in the real system. But anyway the new patch checks the null case and adds a new unit test for this.
