Hairong Kuang commented on HDFS-592:
------------------------------------
As I said, the method is not used only for pipeline recovery, it is also used
for setting up the initial pipeline for append as well. So pipelineRecovery is
not an option. It's hard for a method name to reflect the context under which a
method is called. I don't think any of the client method ever does this. How
about I putting the context in the java doc?
