Modify the
hdfs-site.xml
file.On the NameNode, Secondary NameNode, and all the DataNodes, add the following properties to the
file.$HADOOP_CONF_DIR
/hdfs-site.xmlwhere
$HADOOP_CONF_DIR
is the directory for storing the Hadoop configuration files. For example,/etc/hadoop/conf
.<property> <name>dfs.webhdfs.enabled</name> <value>true</value> </property>
Modify the
core-site.xml
file.On the NameNode, Secondary NameNode, and all the DataNodes, add the following properties to the
file.$HADOOP_CONF_DIR
/core-site.xmlwhere
$HADOOP_CONF_DIR
is the directory for storing the Hadoop configuration files. For example,/etc/hadoop/conf
.<property> <name>hadoop.proxyuser.hue.hosts</name> <value>*</value> </property>
<property> <name>hadoop.proxyuser.hue.groups</name> <value>*</value> </property>
Modify the webhcat-site.xml file. vi $WEBHCAT_CONF_DIR/webhcat-site.xml
<property> <name>webhcat.proxyuser.hue.hosts</name> <value>*</value> </property>
<property> <name>webhcat.proxyuser.hue.groups</name> <value>*</value> </property>
Modify the oozie-site.xml file vi $OOZIE_CONF_DIR/oozie-site.xml
<property> <name>oozie.service.ProxyUserService.proxyuser.hue.hosts</name> <value>*</value> </property>
<property> <name>oozie.service.ProxyUserService.proxyuser.hue.groups</name> <value>*</value> </property>
Stop the NameNode by running the following command:
/usr/lib/hadoop/sbin/hadoop-daemon.sh --config $HADOOP_CONF_DIR stop namenode
Where $HADOOP_CONF_DIR is the directory for storing the Hadoop configuration files. For example,
/etc/hadoop/conf
