[jira] [Commented] (YARN-6214) NullPointer Exception while querying timeline server API
[ https://issues.apache.org/jira/browse/YARN-6214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17056315#comment-17056315 ] Benjamin Kim commented on YARN-6214: The root cause if one of the apps is in init status, some of properties like application type is set to null. So if you make API call with `state=FINISHED` http parameter, you won't face this issue. However, we probably need better error handling logic. > NullPointer Exception while querying timeline server API > > > Key: YARN-6214 > URL: https://issues.apache.org/jira/browse/YARN-6214 > Project: Hadoop YARN > Issue Type: Bug > Components: timelineserver >Affects Versions: 2.7.1 >Reporter: Ravi Teja Chilukuri >Priority: Major > > The apps API works fine and give all applications, including Mapreduce and Tez > http://:8188/ws/v1/applicationhistory/apps > But when queried with application types with these APIs, it fails with > NullpointerException. > http://:8188/ws/v1/applicationhistory/apps?applicationTypes=TEZ > http://:8188/ws/v1/applicationhistory/apps?applicationTypes=MAPREDUCE > NullPointerExceptionjava.lang.NullPointerException > Blocked on this issue as we are not able to run analytics on the tez job > counters on the prod jobs. > Timeline Logs: > |2017-02-22 11:47:57,183 WARN webapp.GenericExceptionHandler > (GenericExceptionHandler.java:toResponse(98)) - INTERNAL_SERVER_ERROR > java.lang.NullPointerException > at > org.apache.hadoop.yarn.server.webapp.WebServices.getApps(WebServices.java:195) > at > org.apache.hadoop.yarn.server.applicationhistoryservice.webapp.AHSWebServices.getApps(AHSWebServices.java:96) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:483) > at > com.sun.jersey.spi.container.JavaMethodInvokerFactory$1.invoke(JavaMethodInvokerFactory.java:60) > at > com.sun.jersey.server.impl.model.method.dispatch.AbstractResourceMethodDispatchProvider$TypeOutInvoker._dispatch(AbstractResourceMethodDispatchProvider.java:185) > at > com.sun.jersey.server.impl.model.method.dispatch.ResourceJavaMethodDispatcher.dispatch(ResourceJavaMethodDispatcher.java:75) > at > com.sun.jersey.server.impl.uri.rules.HttpMethodRule.accept(HttpMethodRule.java:288) > Complete stacktrace: > http://pastebin.com/bRgxVabf -- This message was sent by Atlassian Jira (v8.3.4#803005) - To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
