Apache Hue或Apache Ambari-如何手动安装和配置它们

Question

I am seting up 5 node hadoop 2.5.1 cluster with zookeeper, oozie, hive and hbase. I currently have hadoop 2 and zookeeper installed and running. I want to setup some kind of UI management for all the services so I can monitor health and do admin tasks from it. I see all documents for Ambari and Hue are geared towards Hortornworks and Cloudera respectively. Is there any step-by-step guide for either of these UI console that tells me how to configure them for my existing hadoop services ?

Answer 1

Hue has this blog post about how to integrate with any cluster.

We also recommend this doc . It says Cloudera but this is the same instruction for any Hadoop (as Hue uses only standard APIs).

Answer 2

Officialy, Ambari does not support installation on an existing cluster. When you install it you have to remove previous hadoop components. As mentioned on Ambari FAQ Installing a new cluster on top of an existing cluster

When installing a Hadoop cluster via Ambari on hosts that already have Hadoop bits installed (including an existing cluster deployed via Ambari), perform the following:

Stop all the services on all the nodes(including ganglia and nagios)
It is also a good practice to delete the rpms from all nodes.

search for the rpms:
rpm -qa | grep ganglia
rpm -qa | grep oozie
rpm -qa | grep sqoop
rpm -qa | grep pig
rpm -qa | grep nagios
rpm -qa | grep hadoop

and remove them :
rpm -e <package name>

Answer 3

Hortonworks documentation provides Hue install instructions as well :

Chapter 14. Installing Hue

Hue requires services to be stopped on cluster, no need to remove them like Ambari install requires.
