If you want to see mapreduce jobs, please use "mapred job". "hadoop job" is deprecated. If you want to see all kinds of applications run by your YARN cluster, please use "yarn application". Thanks for the suggestion. I do notice that.But the result is the same though. 2. Job history server only shows the finished mapreduce jobs. There will be another application history server that shows all completed applications run by YARN, but it's not available on 2.2. 3. ResourceManager webUI is not the job history web UI. You should check your yarn-site.xml to see what's the address of the RM webUI. It will list all the applications that RM remembers. - Zhijie On Thu, Feb 20, 2014 at 7:04 PM, Chen, Richard <richard.c...@intel.com<mailto:richard.c...@intel.com>> wrote: Dear group, I compiled hadoop 2.2.0 x64 and running it on a cluster. When I do hadoop job -list or hadoop job -list all, it throws a NPE like this: 14/01/28 17:18:39 INFO Configuration.deprecation: session.id<http://session.id> is deprecated. Instead, use dfs.metrics.session-id 14/01/28 17:18:39 INFO jvm.JvmMetrics: Initializing JVM Metrics with processName=JobTracker, sessionId= Exception in thread "main" java.lang.NullPointerException at org.apache.hadoop.mapreduce.tools.CLI.listJobs(CLI.java:504) at org.apache.hadoop.mapreduce.tools.CLI.run(CLI.java:312) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at org.apache.hadoop.mapred.JobClient.main(JobClient.java:1237) and on hadoop webapp like jobhistory ( I turn on the jobhistory server). It shows no job was running and no job finishing although I was running jobs. Please help me to solve this problem. Thanks!!
