Konstantin Shvachko updated HADOOP-5314:
----------------------------------------
Component/s: dfs
The problem is that on the very first iteration of the loop {{needToSave}} is
set to true and cannot be reset to false after that. It happens because
{{checkpointTime}} never equals {{Long.MIN_VALUE}} while both
{{latestNameCheckpointTime}} and {{latestEditsCheckpointTime}} do.
> needToSave incorrectly calculated in loadFSImage()
> --------------------------------------------------

> {{FSImage.loadFSImage()}} incorrectly calculates the value of {{needToSave
> }}, which is always true and results in saving image at startup even if that
> is not necessary.
