Konstantin Shvachko commented on HDFS-624:
------------------------------------------
I agree about naming ReplicaNotFoundException and getNewGenerationStamp.
For {{ClientProtocol.updatePipeline()}} should we rather adopt the following
signature:
{code}
updatePipeline(String clientName, Block oldBlock, Block newBlock, DatanodeID[]
newNodes)
{code}
> Client support pipeline recovery
