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.
> Allow client to get a new generation stamp from NameNode
