Hue is an open-source Web interface that supports Apache Hadoop and its ecosystem
Hue aggregates the most common Apache Hadoop components into a single interface and targets the user experience. Its main goal is to have the users "just use" Hadoop without worrying about the underlying complexity or using a command line.
This charm leverages our pluggable Hadoop model with the
interface. This means that you will need to deploy a base Apache Hadoop cluster
to run Hue.
You may manually deploy the recommended environment as follows:
juju deploy apache-hadoop-namenode namenode juju deploy apache-hadoop-resourcemanager resourcemanager juju deploy apache-hadoop-slave slave juju deploy apache-hadoop-plugin plugin juju deploy hue hue juju add-relation resourcemanager namenode juju add-relation slave resourcemanager juju add-relation slave namenode juju add-relation plugin resourcemanager juju add-relation plugin namenode juju add-relation plugin hue
At this point you will then need to expose hue:
juju expose hue
And then browse to the HUE_IP:HUE_PORT shown in 'juju status --format tabular'
The reason for this is that the first login to hue via the web interface creates the default admin user so we need to make sure you are the first person to log in.
The allowed Hadoop cluster operations should be available from the web interface. By default HDFS file browsing and Hadoop job browsing should be available. Additional features will be made available as you relate Hue to other charms, as described below.
Enabling Apache Hive features
Adding Apache Hive features to Hue is as simple as deploying the Hive charm and relating it to Hue. First, deploy Hive/MySQL:
juju deploy mysql juju set mysql binlog-format=ROW juju deploy apache-hive hive juju add-relation plugin hive
Now, add a relation between Hive and Hue:
juju add-relation hue hive
Hue should restart, and you should be able to query Hive and browse the metasotre from the updated Hue UI.
Enabling Apache Zookeeper features
Hue interacts with Zookeeper through a REST API. Relate Hue to Zookeeper as follows:
juju deploy apache-zookeeper zookeeper juju set zookeeper rest=true
Now, add a relation between Zookeeper and Hue:
juju add-relation hue zookeeper
Hue should restart, and you should be able to browse Zookeeper from the updated Hue UI.
