Install the Hadoop HttpFS component on the Hue server.

For RHEL/CentOS/Oracle Linux:

yum install hadoop-httpfs

For SLES:

yum install hadoop-httpfs

Modify /etc/hadoop-httpfs/conf/httpfs-env.sh to add the JDK path. In the file, ensure that JAVA_HOME is set:

export JAVA_HOME=/usr/jdk64/jdk1.7.0_67

Configure the HttpFS service script for use by setting up the symlink in /etc/init.d:

> ln -s /usr/hdp/{HDP2.3.x version number}/etc/rc.d/init.d/hadoop-httpfs /etc/init.d/hadoop-httpfs

For example, {HDP2.3.x version number} could be '2.3.4.0-$BUILD'.

Modify /etc/hadoop-httpfs/conf/httpfs-site.xml to configure HttpFS to talk to the cluster, by confirming that the following properties are correct:

<property>
 <name>httpfs.proxyuser.hue.hosts</name>
 <value>*</value>
</property>

<property>
 <name>httpfs.proxyuser.hue.groups</name>
 <value>*</value>
</property>

Start the HttpFS service.

service hadoop-httpfs start 

Modify the core-site.xml file. On the NameNodes and all the DataNodes, add the following properties to the $HADOOP_CONF_DIR /core-site.xml file, where $HADOOP_CONF_DIR is the directory for storing the Hadoop configuration files. For example, /etc/hadoop/conf.

<property>
 <name>hadoop.proxyuser.httpfs.groups</name>
 <value>*</value>
</property>

<property>
 <name>hadoop.proxyuser.httpfs.hosts</name>
 <value>*</value>
</property>

In the hue.ini file, under the [hadoop][[hdfs_clusters]][[[default]]] subsection, use the following variables to configure the cluster:

Restart Hue for the changes to take effect.

service hue restart
