Todd Lipcon commented on HDFS-1073:
-----------------------------------
I agree. I put one proposal that I'm partial to here:
https://issues.apache.org/jira/browse/HDFS-955?focusedCommentId=12832706&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12832706
The "#3" solution in the above comment I think is (a) reasonably simple, and
(b) can be very easily made to keep around some number of trailing image/edit
files in case of corruption bugs.
Is this the sort of thing you're investigating for this JIRA, Sanjay?
