Can you check your Java environment 

$ which -a java

Are you executing the java command as a non-root user? /var/log/hadoop/hdfs/jsvc.out’ for reading: Permission denied What are the permissions and ownership?

Modify the JAVA_HOME value in the hadoop-env.sh file:

export JAVA_HOME=/usr/java/default


Start the data node

su -l hdfs -c "/usr/hdp/current/hadoop-hdfs-datanode/../hadoop/sbin/hadoop-daemon.sh start datanode"
