Kan Zhang commented on HDFS-592:
--------------------------------
In the spirit of addBlock(), how about we use recoverPipeline()? I guess what
happens here is you don't want add a new appendBlock() call for the initial
pipeline setup for append and instead want to re-use the recoverPipeline()
call, which is fine. However, in the absence of a better name for both
recoverPipeline and appendBlock, I can live with recoverPipeline than something
totally non-descriptive, like getNewStampAndToken().
> Allow client to get a new generation stamp from NameNode
