Summary: DecommissioningNodesWatcher#logDecommissioningNodesStatus
calculate app elapsed time error
Key: YARN-11213
URL: https://issues.apache.org/jira/browse/YARN-11213
Project: Hadoop YARN
Issue Type: Bug
Reporter: liu bin
There is a calculation in
DecommissioningNodesWatcher#logDecommissioningNodesStatus to calculate app
elapsed time:
{code:java}
(mclock.getTime() - rmApp.getStartTime()) / 1000{code}
But mclock.getTime() is get from System.nanoTime() /
NANOSECONDS_PER_MILLISECOND, rmApp.getStartTime() is get from
System.currentTimeMillis(), they cannot be compared.
This calculation should be:
{code:java}
(System.currentTimeMillis() - rmApp.getStartTime()) / 1000{code}
