Work Description: aihuaxu opened a new pull request #2430:
URL: https://github.com/apache/hadoop/pull/2430
Standby namenode does the checkpoint and uploads the image to the other
active/observer namenodes. If other namenodes, e.g., observers are down for
maintenance, currently uploading will fail and retrigger the checkpoint and
image uploading immediately. That is causing unnecessary network traffic. This
patch logs a message when unloading fails and continue with the regular
checkpoint schedule.
