Chris Trezzo commented on YARN-5797:
------------------------------------
The checkstyle warning is because the
{{TestResourceLocalizationService#testDownloadingResourcesOnContainerKill}}
method is over 150 lines:
bq.
./hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/test/java/org/apache/hadoop/yarn/server/nodemanager/containermanager/localizer/TestResourceLocalizationService.java:1128:
@Test(timeout = 20000):3: Method length is 242 lines (max allowed is 150).
This patch barely touches the method (i.e. changes 1 line) so I think it would
be wrong to refactor this method as part of this patch. I will file a jira to
address the method refactor.
Thanks!
