Mark S created YARN-4540:
----------------------------
Summary: Yarn property
"yarn.nodemanager.localizer.cache.cleanup.interval-ms" not working as expected
Key: YARN-4540
URL: https://issues.apache.org/jira/browse/YARN-4540
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.7.1
Environment: Ambari – Version 2.1.2.1
YARN - Version 2.7.1.2.3
HDP - Version 2.3.2.0
Reporter: Mark S
Priority: Minor
I manually add specific YARN configuration to reduce my YARN cache size,
however it does not get updated for the interval specified by:
{code}
yarn.nodemanager.localizer.cache.cleanup.interval-ms
{code}
I did notice that eventually my server did reduce my YARN cache size over the
weekend.
h5. Set Values (Should update size in 1 minute):
{code}
yarn.nodemanager.localizer.cache.target-size-mb=4096
yarn.nodemanager.localizer.cache.cleanup.interval-ms=60000
{code}
h5. Default values (Should update size in 10 minutes):
{code}
yarn.nodemanager.localizer.cache.target-size-mb=10240
yarn.nodemanager.localizer.cache.cleanup.interval-ms=600000
{code}
h5. Confirming YARN cache size
{code}
date && du -m /hadoop/yarn | sort -nr | head -n 20
#date && du -m . | sort -nr | head -n 20
{code}
