As a Yellowfin cluster requires only one database instance, it means tha= t the Yellowfin installation process will differ slightly when installing a= cluster. The first Yellowfin cluster node can be installed the same way as= a standalone instance of Yellowfin. The command-line or GUI installer can = be used.
Additional Yellowfin Cluster nodes do not require the Yellowfin database= . There are several ways for installing additional nodes:
After the initial node is installed, and the Yellowfin database is creat= ed, the Yellowfin installer can be used for the installation of subsequent = nodes without affecting the initial database.
Use the Yellowfin Installer using the command:
java -j= ar yellowfin-20170928-full.jar action.nodbaccess=3Dtrue
The action.nodbaccess=3Dtrue opt= ion will run the installer as usual, and prompt for database credentials, b= ut not create or alter the database during installation. This will only gen= erate the filesystem component of Yellowfin. If Legacy Clustering is used, = individual changes may need to be made to the web.xml file on each of the n= odes.
As the filesystem structure on each node is the same, a new node can be = created by duplicating the Yellowfin installation directory onto another co= mputer. If Legacy Clustering is used, changes will need to be made to the w= eb.xml file on each node.
A Virtual Machine (or AWS AMI or Azure Compute image or Docker image) co= uld be pre-configured with the Application Server component of Yellowfin. A= copy of the Virtual Machine could be started for each application node in = a cluster.
