Some suggestion: change user permision to allow me to read the Hadoop output because Hadopp owns all by default ????on the Scratch disk
Or use provided script: fixperms.sh /global/scratch/sd/balewski/hadoop/wordcount- gpfs/
hadoop jar /usr/common/tig/hadoop/hadoop-0.20.2+228/hadoop-0.20.2+228-examples.jar wordcount -Dmapred.reduce.tasks=4 wordcount-in wordcount-op
