Haohui Mai commented on HDFS-6673:
----------------------------------
bq. Also, even a 40GB image easily fits in memory on server these days.
The whole point of this tool is to run the oiv on machines that do not have the
luxury of abundant memory. Can you clarify what point you are trying to make?
bq. These seem like pretty big drawbacks to me, and are addressed by this tool.
I think calling it "half-baked" is unfair considering it provides greater
functionality.
Can you clarify what the greater functionality are? The Delimiter only outputs
mtime/atime and other information available from legacy fsimage.
BTW, if you really want to commit this please update the document to explicit
state that the tool will not work for large fsimage, so that the users won't be
caught by surprise.
