Naganarasimha G R commented on YARN-6517: ----------------------------------------- [~cheersyang], Bad on my part, Findbugs issue was still existent on the last patch can you have a look at it ? though the build is not available you can refer this [link|https://builds.apache.org/job/PreCommit-YARN-Build/16184/artifact/patchprocess/branch-findbugs-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-common-warnings.html#NP_NULL_ON_SOME_PATH_FROM_RETURN_VALUE] from YARN-5006 i think we can do something like below to avoid {code} File[] filesList ; if(containerLogDir == null || (filesList = containerLogDir.listFiles()) == null) { return new HashSet<>(0); } Set<File> candidates = new HashSet<File>(Arrays.asList(filesList)); {code} if you still have problems then we can add it to the exception list. > Fix warnings from Spotbugs in hadoop-yarn-common > ------------------------------------------------ > > Key: YARN-6517 > URL: https://issues.apache.org/jira/browse/YARN-6517 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Weiwei Yang > Assignee: Weiwei Yang > Labels: findbugs > Fix For: 2.9.0, 3.0.0-alpha4 > > Attachments: YARN-6517.001.patch, YARN-6517.002.patch > > > There are 2 findbugs warnings in hadoop-yarn-common project since switched to > spotbugs, > # Possible null pointer dereference in > org.apache.hadoop.yarn.logaggregation.AggregatedLogFormat$LogValue.getPendingLogFilesToUpload(File) > due to return value of called method > # Possible null pointer dereference in > org.apache.hadoop.yarn.util.ProcfsBasedProcessTree.getProcessList() due to > return value of called method > see more in > [https://builds.apache.org/job/PreCommit-HADOOP-Build/12157/artifact/patchprocess/branch-findbugs-hadoop-yarn-project_hadoop-yarn_hadoop-yarn-common-warnings.html] -- 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
