------------------------------------
Summary: Set
yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage
to a higher value in tests
Key: OOZIE-2731
URL: https://issues.apache.org/jira/browse/OOZIE-2731
Project: Oozie
Issue Type: Improvement
Components: tests
Affects Versions: trunk
Reporter: Robert Kanter
Assignee: Attila Sasvari
Priority: Minor
Fix For: trunk
We should set
{{yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage}}
to a higher value in the mini cluster during tests (default is {{90.0}}).
This property determines the maximum percentage of disk space that can be
utilized before the NodeManager goes to unhealthy and won't run any tasks.
As-is, this means that if you have < 10% of your disk free, unit tests that
submit Yarn jobs will fail because they can't run the job; and it's not always
clear that this is the problem.
We should set this to a higher value such as {{99.0}}. Our unit tests don't
need _that_ much disk space.
