Committing this. > Use separate threshold configurations for disk-full detection and > disk-not-full detection. > ------------------------------------------------------------------------------------------ > > Key: YARN-3943 > URL: https://issues.apache.org/jira/browse/YARN-3943 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Reporter: zhihai xu > Assignee: zhihai xu > Priority: Critical > Attachments: YARN-3943.000.patch, YARN-3943.001.patch, > YARN-3943.002.patch > > > Use separate threshold configurations to check when disks become full and > when disks become good. Currently the configuration > "yarn.nodemanager.disk-health-checker.max-disk-utilization-per-disk-percentage" > and "yarn.nodemanager.disk-health-checker.min-free-space-per-disk-mb" are > used to check both when disks become full and when disks become good. It will > be better to use two configurations: one is used when disks become full from > not-full and the other one is used when disks become not-full from full. So > we can avoid oscillating frequently. > For example: we can set the one for disk-full detection higher than the one > for disk-not-full detection. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
