when i go to the job history server http://hadoop-cluster:19888/jobhistory
i see no map reduce job there. i ran 3 simple mr jobs successfully. i verified by the console output and hdfs output directory. all i see on the UI is: No data available in table. any ideas? unless there is a JobHistoryServer just for MapReduce.. where is that?
