Hi All,
I can start the hadoop by typing start-dfs.sh and start-mapred.sh. But when
i use the start-all.sh only the hdfs is start. The jobtracker's log
indicate there is an exception when starting the job-tracker.
2009-06-01 22:06:59,675 INFO org.apache.hadoop.mapred.JobTracker: problem

is this exception cause by no time delay between the start-dfs.sh and the
start-mapred.sh script? Thanks.
