----------------------------------
Summary: Fix inconsistent priority ordering in Priority and
SchedulerRequestKey
Key: YARN-7676
URL: https://issues.apache.org/jira/browse/YARN-7676
Project: Hadoop YARN
Issue Type: Bug
Reporter: Botong Huang
Assignee: Botong Huang
Priority: Minor
Today the priority ordering in _Priority.compareTo()_ and
_SchedulerRequestKey.compareTo()_ is inconsistent. Both _compareTo_ method is
trying to reverse the order:
P0.compareTo(P1) > 0, meaning priority wise P0 < P1. However,
SK(P0).comapreTo(SK(P1)) < 0, meaning priority wise SK(P0) > SK(P1).
This is attempting to fix that by undo both reversing logic. So that priority
wise P0 > P1 and SK(P0) > SK(P1).
