Naganarasimha G R updated YARN-6515: ------------------------------------ Attachment: YARN-6515.002.patch Sorry for keeping this jira pending since a long time, was not sure whether to go ahead with the fix for the find bug report in DockerLinuxContainerRuntime. To proceed for other issues i have uploaded a patch excluding it. [~miklos.szeg...@cloudera.com], would you mind handling the findbug issue in {{DockerLinuxContainerRuntime}} in YARN-6757 or new jira? cc / [~ajisakaa] > Fix warnings from Spotbugs in hadoop-yarn-server-nodemanager > ------------------------------------------------------------ > > Key: YARN-6515 > URL: https://issues.apache.org/jira/browse/YARN-6515 > Project: Hadoop YARN > Issue Type: Bug > Components: nodemanager > Reporter: Naganarasimha G R > Assignee: Naganarasimha G R > Attachments: YARN-6515.001.patch, YARN-6515.002.patch > > > 5 find bugs issue was reported NM project as part of the YARN-4166 [build| > https://builds.apache.org/job/PreCommit-YARN-Build/15694/artifact/patchprocess/branch-findbugs-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-server_hadoop-yarn-server-nodemanager-warnings.html] > Issue 1: > > org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainerMetrics.usageMetrics > is a mutable collection which should be package protected > Bug type MS_MUTABLE_COLLECTION_PKGPROTECT (click for details) > In class > org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainerMetrics > Field > org.apache.hadoop.yarn.server.nodemanager.containermanager.monitor.ContainerMetrics.usageMetrics > At ContainerMetrics.java:\[line 134\] > Issue 2: > > org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ContainerLocalizer.createStatus() > makes inefficient use of keySet iterator instead of entrySet iterator > Bug type WMI_WRONG_MAP_ITERATOR (click for details) > In class > org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ContainerLocalizer > In method > org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ContainerLocalizer.createStatus() > Field > org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ContainerLocalizer.pendingResources > At ContainerLocalizer.java:\[line 334\] > Issue 3: > org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.removeVeryOldStoppedContainersFromCache() > makes inefficient use of keySet iterator instead of entrySet iterator > Bug type WMI_WRONG_MAP_ITERATOR (click for details) > In class org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl > In method > org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.removeVeryOldStoppedContainersFromCache() > Field > org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.recentlyStoppedContainers > At NodeStatusUpdaterImpl.java:\[line 721\] > Issue 4: > Hard coded reference to an absolute pathname in > org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.runtime.DockerLinuxContainerRuntime.launchContainer(ContainerRuntimeContext) > Bug type DMI_HARDCODED_ABSOLUTE_FILENAME (click for details) > In class > org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.runtime.DockerLinuxContainerRuntime > In method > org.apache.hadoop.yarn.server.nodemanager.containermanager.linux.runtime.DockerLinuxContainerRuntime.launchContainer(ContainerRuntimeContext) > File name /sys/fs/cgroup > At DockerLinuxContainerRuntime.java:\[line 455\] > Useless object stored in variable removedNullContainers of method > org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.removeOrTrackCompletedContainersFromContext(List) > Bug type UC_USELESS_OBJECT (click for details) > In class org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl > In method > org.apache.hadoop.yarn.server.nodemanager.NodeStatusUpdaterImpl.removeOrTrackCompletedContainersFromContext(List) > Value removedNullContainers > Type java.util.HashSet > At NodeStatusUpdaterImpl.java:\[line 644\] -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
