Installed Components
A VectorH instance requires a fully configured Hadoop installation and consists of the following installed components:
• VectorH full installation on the first Hadoop DataNode.
This can be the NameNode if it doubles as a DataNode, but on production clusters we recommend that the NameNode and DataNode be separate because the NameNode is typically the busiest node in the cluster, and the VectorH master node is the busiest node in the VectorH instance. We refer to the node with the full VectorH installation as the master node.
• Potentially a full Vector installation on one other DataNode for the master node failover infrastructure
• Vector Server, libraries, Java classes on the slave nodes
• Intel MPI Runtime library on all nodes for inter-node communication
