Suresh Srinivas commented on HDFS-624:
--------------------------------------
Comments:
# getNewStampForPipeline - is it better to rename this as getNewGenerationStamp?
# DFSClient.java - ResponseProcessor.run() - To avoid a warning in style check
for empty block, can the if statement be changed to {{ if (seqno != -2) }}
# ResponseProcessor.run() - In the for loop before throwing exception should
{{responderClosed = true}} be set?
# ResponseProcessor.run() - why is the try - catch block not inside the for
loop? Is setting errorIndex to 0 fine?
> Client support pipeline recovery
