Hi Deva, Tried the yarn application path with absolute values. Still it didn't work. It failed with same stack trace:-( Now the value of yarn.application.classpath was: /usr/local/hadoop/etc/hadoop,/usr/local/hadoop/*,/usr/local/hadoop/lib/*,/usr/local/hadoop/*,/usr/local/hadoop/lib/*,/usr/local/hadoop/*,/usr/local/hadoop/lib/*,/usr/local/hadoop/*,/usr/local/hadoop/*
