Kan Zhang commented on HDFS-592:
--------------------------------

sorry, I forgot pipeline will not be created right after append() call. In that 
case, the client can use pipelineRecovery() call to get an access token since 
it already holds the lease.

> Allow client to get a new generation stamp from NameNode
