hadoop rumen question
张伟 2013-08-19, 12:15
Now I want to use Gridmix to do some tests. Firstly I should use rumen to generate a job trace file.
I use hadoop 1.0.4. However, when I use the command
hadoop@mastertest:~/hadoop-scheduler/hadoop-1.0.4$ ./bin/hadoop jar hadoop-tools-1.0.4.jar org.apache.hadoop.tools.rumen.TraceBuilder file:///home/hadoop/job-trace.json file:///home/hadoop/hadoop-scheduler/hadoop-1.0.4/logs/history/done
I got the following errors. Can someone give me some guidance which part brings this problem?
