Tsz Wo (Nicholas), SZE commented on HADOOP-4225:
------------------------------------------------
I think the correct way to fix this is changing logOpenFile(...) to write only
mtime but not atime. However, this will introduce a layout change.
+1 to the patch. Konstantin's change makes the code more clear. Otherwise, it
is hard to understand why writing the same number twice.
> FSEditLog logs modification time instead of access time.
