Cluster Big Data 1

Cluster Big Data 1

Service description

Cluster for experimentation and research in big data. Its objective is to provide an adequate hardware platform for Big Data jobs with a very flexible configuration, to make it easy to research and experiment on it.


You have to register filling the requests and problem reporting form. This form is only available to CITIUS users.


The cluster can be accessed only through the master node which acts as a frontend for the cluster:

ssh -X <citius user>

To access the Ambari manager web interface, you need to tunnel the nodo1 port 8080 using SSH. In case you want to use this interface, you must use this command instead:

ssh -L 8080:nodo1:8080 <citius_user>


To manage the cluster from the Apache Ambari web interface, once connected through SSH using the option -L 8080:nodo1:8080, connect to http://localhost:8080/

User and password are admin/admin.


The following software can be managed from the Ambari console:

  • HDFS 2.7.3
  • YARN 2.7.3
  • Tez 0.7.0
  • Hive 1.2.1000
