Hi, I have deployed a multi-node cluster with one master and two data nodes. Here's what jps shows:
hadoop@hadoop-master:~$ jps 24641 SecondaryNameNode 24435 DataNode 24261 NameNode 24791 ResourceManager 25483 Jps 24940 NodeManager hadoop@hadoop-data1:~$ jps 15556 DataNode 16198 NodeManager 16399 Jps hadoop@hadoop-data2:~$ jps 16418 Jps 15575 DataNode 16216 NodeManager When I open the web console, I only see one node running: http://screencast.com/t/E6yehRvUbt Where are the other two nodes? Why don't they show up? Next I run one of the example scripts hadoop@hadoop-master:~$ hadoop jar /usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar pi 10 30 Number of Maps = 10 Samples per Map = 30 Wrote input for Map #0 Wrote input for Map #1 ... Job Finished in 2.956 seconds Estimated value of Pi is 3.14146666666666666667 I can't see this anywhere in the web interface. I thought it might show in the Applications sub-menu. Should I be able to see this? It appears to run successfully. Daniel
