[jira] [Commented] (YARN-4540) Yarn property "yarn.nodemanager.localizer.cache.cleanup.interval-ms" not working as expected
[ https://issues.apache.org/jira/browse/YARN-4540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel=15093111#comment-15093111 ] Kai Sasaki commented on YARN-4540: -- Sorry for misunderstanding. How can you put a log files without running jobs on YARN? Do you mean put or generate log files by yourself under "/hadoop/yarn/local"? My assumption is that you decreased "yarn.nodemanager.localizer.cache.target-size-mb" one by one. And caches were deleted under the target-size-mb correctly. But it takes more time than "yarn.nodemanger.localizer.cache.cleanup.interval-ms".

Basically I ran a lot of YARN jobs and noticed that the "/hadoop/yarn/local/usercache/" directory grew to about 10 GB. I then stopped all my YARN jobs. Then I attempted to reduce the "/hadoop/yarn/local/usercache/" directory size by setting the "yarn.nodemanager.localizer.cache.target-size-mb" property and waiting. In response to your last question. Yes, it seemed that the caches where deleted to the target size, but in a much greater time interval then specified in the "yarn.nodemanger.localizer.cache.cleanup.interval-ms" property. > 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, yarn >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 > Original Estimate: 1h > Remaining Estimate: 1h > > 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.

The "/hadoop/yarn/local/usercache//filecache" is a total of 3752 MB in size. Also the command shown above "date && du -m /hadoop/yarn/ | sort -nr | head -n 20" is specifically showing only the top 20 values ("head -n 20"), so there is a whole bunch of filecache sizes not shown. As such, the calculation mentioning "163 * 15" is only the sum of a partial set. Just a quick update to try and clear up any misunderstanding. I was NOT running any YARN jobs (My Hadoop cluster is for testing and was idle), and as such the directory "/hadoop/yarn/local" was at a stable constant size. Initially my "/hadoop/yarn/local" size was around 10 GB, and then I updated "yarn.nodemanager.localizer.cache.target-size-mb" to a much smaller value (Think around half). Then I ran the test again when the "/hadoop/yarn/local" size was around 5GB and set the "yarn.nodemanager.localizer.cache.target-size-mb" property to about 4GB. Then I ran another test. My "/hadoop/yarn/local" size was around 4GB and I set the "yarn.nodemanager.localizer.cache.target-size-mb" property to about 3 GB. > 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, yarn >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 > Original Estimate: 1h > Remaining Estimate: 1h > > 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.

In the case, the total of resources can be the sum of {{/hadoop/yarn/local/usercache//filecache/*}} sizes. In other words 163 * 15 = 2475. It does not exceed 3072 at 13:11. It seems to exceed 3072MB at 13:25 according the log.
