You might also enable debug in: hadoop-env.sh
# Extra Java runtime options. Empty by default.
export HADOOP_OPTS="$HADOOP_OPTS -Djava.net.preferIPv4Stack=true
-Dsun.security.krb5.debug=true ${HADOOP_OPTS}”
and check that the principals are the same on the NameNode and DataNode.
and you can confirm the same on all nodes in hdfs-site.xml.
You can also ensure all nodes in the cluster are kerberized in core-site.xml
(no auth by default) :
<property>
<name>hadoop.security.authentication</name>
<value>kerberos</value>
<description>Set the authentication for the cluster. Valid values are:
simple or kerberos.
</description>
</property>
