Subject Re: DesignLounge @ HadoopSummit

Should we talk about making HDFS operations idempotent in the spirit of
HDFS-4849 and HDFS-4872?
Physical discussions may be more efficient, which can save us jira writing
time.
I can work on a short summary of what was discussed so far, proposed
approaches.

Thanks,
--Konstantin
