hadoop wordcount example erreor: Task process exit with nonzero status of 1

问题

I am running 3 node cluster on Ubuntu 12.04 LTS Server and hadoop 1.2.1 installed on it with JDK 1.7, now for very first check whether map-reduce jobs are executing or not I executed wordcount from hadoop-examples-1.2.1.jar and got the stunning error:

After getting this error I executed sqoop import from SQL server 2008 R2 in which I am getting same error. My job's log file also has same error. I also verified by web UI that my cluster's heap size is 200 MB. So, to me memory doesn't seem problematic also userlogs are also there is hadoop.temp.dir (/var/lib/hadoop) and stderr file of logs says:

execvp: Permission denied

Please let me know what should I do to resolve this issue.
