Hi, I have set up a single node Hadoop 2.2.0 . I can submit wordcount hadoop job to YARN from the command line. It run successfully and I checked the result is in hdfs. matmsh@gauss:~> hadoop jar ~/installed/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.2.0.jar wordcount input output6 14/06/28 13:40:00 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 14/06/28 13:40:00 INFO Configuration.deprecation: session.id is deprecated.

However, the above job does not show up at the web UI : http://localhost:8088/cluster/apps My configurations are below, mapred-site.xml : <configuration> <property> <value>mapreduce.framework.name</value> <name>yarn</name> </property> </configuration> ------- hdfs-site.xml <configuration> <property> <name>dfs.replication</name> <value>1</value> </property> <property> <name>dfs.namenode.name.dir</name> <value>file:/home/matmsh/temp/hadoop2/namenode</value> <description>The name of the default file system.</description> </property> <property> <name>dfs.datanode.data.dir</name> <value>file:/home/matmsh/temp/hadoop2/datanode</value> <description>The name of the default file system.</description> </property> </configuration> ---------------- yarn-site.xml <configuration> <!-- Site specific YARN configuration properties --> <property> <name>yarn.nodemanager.aux-services</name> <value>mapreduce_shuffle</value> </property> <property> <name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name> <value>org.apache.hadoop.mapred.ShuffleHandler</value> </property> </configuration> ------------------------------------ What other configurations are needed to show the job in the web UI ? Thanks in advance for any assistance ! Shing
