> After formatting a NameNode and inspecting its VERSION file, the cTime
> property shows 0. The value does get updated to current time during an
> upgrade, but I believe this is intended to be the creation time of the
> cluster, and therefore the initial value of 0 before an upgrade can cause
> confusion.
