> There is a calculation in
> DecommissioningNodesWatcher#logDecommissioningNodesStatus to calculate app
> elapsed time:
> {code:java}
> (mclock.getTime() - rmApp.getStartTime()) / 1000{code}
> But mclock.getTime() is generated from System.nanoTime() /
> NANOSECONDS_PER_MILLISECOND,
> rmApp.getStartTime() is generated from System.currentTimeMillis(), they
> cannot be compared.
> This calculation should be:
> {code:java}
> (System.currentTimeMillis() - rmApp.getStartTime()) / 1000{code}
