liu bin updated YARN-11213:
---------------------------
Description:
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}
was:
