same edits file is loaded more than once

[lei liu]

I am using hadoop0.20.2, now I want to use HDFS HA function.  I research
AvatarNode. I find if the StandbyNN do checkpoint fail, when next time the
StandbyNN do checkpoint, the same edits file is loaded again.  Can same
edits file be loaded more than once in hadoop0.20.2?
if not, what is the harm?

Thanks,
