Junping Du commented on YARN-3019:
----------------------------------
bq. To clarify: this jira is to flip recovery mode to work-preserving recovery
from non-work-preserving recovery. The feature itself remains disabled. i.e.
"yarn.resourcemanager.recovery.enabled" remains false. updating the
description.
Can you explain the behavior different with
"yarn.resourcemanager.work-preserving-recovery.enabled" to be true while
"yarn.resourcemanager.recovery.enabled" to be false? Is there any solid
scenario for this configuration combination or only for identifying bug
purpose? For latter one, more convenient way could apply on individual cluster
rather than trunk. Thoughts?
