While I was looking into TestDistributedShell logs, I noticed the following {{Warning}} {code:bash} 2020-12-29 16:22:26,379 INFO [Time-limited test] handler.ContextHandler (ContextHandler.java:doStart(824)) - Started o.e.j.s.ServletContextHandler@75389179{logs,/logs,file:///hadoop-yarn-project/hadoop-yarn/hadoop-yarn-applications/hadoop-yarn-applications-distributedshell/target/log,AVAILABLE} 2020-12-29 16:22:26,380 INFO [Time-limited test] handler.ContextHandler (ContextHandler.java:doStart(824)) - Started o.e.j.s.ServletContextHandler@116ed75c{static,/static,jar:file:~/.m2/repository/org/apache/hadoop/hadoop-yarn-common/3.4.0-SNAPSHOT/hadoop-yarn-common-3.4.0-SNAPSHOT.jar!/webapps/static,AVAILABLE} 2020-12-29 16:22:26,390 WARN [Time-limited test] webapp.WebInfConfiguration (WebInfConfiguration.java:getCanonicalNameForWebAppTmpDir(794)) - Can't generate resourceBase as part of webapp tmp dir name: java.lang.NullPointerException 2020-12-29 16:22:26,469 INFO [Time-limited test] util.TypeUtil (TypeUtil.java:<clinit>(201)) - JVM Runtime does not support Modules {code} For OS X, it looks like {{webAppContext.setBaseResource}} and accessing the sources from a jar file will cause {{file.resource.toURI().getPath()}} to return {{null}} for {{jar:-urls}} I checked that changing the jetty-version from {{9.4.20.v20190813}} to something above {{9.4.21}} (aka., 9.4.23.v20191118) fixes the warning. [~inigoiri], [~aajisaka], [~weichiu], [~ayushtkn] Do you guys think we should consider upgrading Jetty to the [latest versions of 9.4.x|https://mvnrepository.com/artifact/org.eclipse.jetty/jetty-webapp] like 9.4.35? -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
