In a previous article I have explained how to create a simple 4-nodes Hadoop cluster using Cloudera 4. Cloudera has released a beta of the version 5, so I decided to give it a try!
Installation
The procedure remains unchanged, apart from the installer binary path. The following binary installer should be used:
curl -O http://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin ...
The command line installer installs everything required to setup the Hadoop Cluster (including Java 1.7 and the database):
Connect to the website installed on the first node of the cluster, (for example http://hadoop1.example.com:7180) and logon using admin/admin. The installation procedure then continues. The steps are very similar compared to CDH4.5. There is only one parcel to install: Impala and Solr are now part of the main CDH5 parcel.
The Cloudera 5 beta installer worked flawlessly and in minutes I was operational.
Cloudera Manager 5
The Cloudera Manager 5.0 main page (running on port 7180 of your first node) is very familiar, and is almost similar to the version 4.5:
Hue 3.0
On the other hand Hue version 3.0.0, delivered with this installation, has changed a lot. The interface is streamlined and user friendly:
Conclusion
I have been able to install my new Hadoop cluster, with YARN, JDK7 and CDH 5 in less than an hour without any issue. I’m now busy exploring…
