[Note: to be able to submit jobs to our hadoop cluster, a directory has to be created for you. Ask the CS professor sponsoring your work to request one.]
To submit (a sample) job:
cd hadoop-0.20.203.0 bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'
One user reported an error trying to submit the example saying "Input path does not exist." He was able to fix this with the commandTo review the output:bin/hadoop dfs -mkdir input
bin/hadoop fs -get output output cat output/*
