Konstantin Shvachko updated HADOOP-4225:
----------------------------------------
Attachment: LogATime.patch
I am not arguing about the semantics of the access time field, I am saying that
when saving it into the edits log you should save exactly that field rather
than another one.
So, if you want to set accessTime to the value of the modificationTime you
assign that value to that field. But when you serialize accessTime in
{{logOpenFile()}} to the disk you should serialize that field rather than
something else. I cannot even understand which of them (the first or the
second) corresponds to which time until I look at the loading code.
This is what I mean.
> FSEditLog logs modification time instead of access time.
