I had checked that hadoop classpath and yarn classpath is set already
{{[hadoop@localhost ~]$ hadoop classpath
/home/hadoop/hadoop/etc/hadoop:/home/hadoop/hadoop/share/hadoop/common/lib/*:/home/hadoop/hadoop/share/hadoop/common/*:/home/hadoop/hadoop/share/hadoop/hdfs:/home/hadoop/hadoop/share/hadoop/hdfs/lib/*:/home/hadoop/hadoop/share/hadoop/hdfs/*:/home/hadoop/hadoop/share/hadoop/mapreduce/lib/*:/home/hadoop/hadoop/share/hadoop/mapreduce/*:/home/hadoop/hadoop/share/hadoop/yarn:/home/hadoop/hadoop/share/hadoop/yarn/lib/*:/home/hadoop/hadoop/share/hadoop/yarn/*

also set in *zeppelin-env.sh*
{{export USE_HADOOP=True
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop}}
