What Are Edge Nodes?
Edge nodes, also known as edge communication nodes and gateway nodes, are cluster instances that connect the user’s machine to the cluster’s machines.
They allow users to perform their jobs on the edge node rather than the master nodes, which are crucial to the system’s general operation that helps in avoiding capacity losses on these nodes.
Bridging Hadoop Cluster and External Network
Edge nodes provide the interaction between the Hadoop cluster and the external network.
Edge nodes are mainly used to deploy cluster-admin tools and client applications to provide a uniform experience to everyone with access to them.
Isolated Access Points for Required Services
You can utilize your required services without communicating to any other instance since every cluster program has a client deployed on every single edge node.
As a result, the edge nodes are the only computers whose potential is influenced by user actions.
Enabling Independent User Access
It allows you to offer each user their own node to use the cluster as an independent entity.
It also enables the re-spawning of a new edge node if the previous one has become sufficiently changed, even though an altered master can cause the entire cluster to be damaged.
Enhancing Performance
Some nodes have critical activities that, if disrupted, might negatively influence performance.
Edge nodes provide network access for the cluster, allowing end-users to communicate with worker nodes as needed without exposing the whole cluster to communication.
This restriction enhances the dependability and security of the system.
As work is fairly divided amongst work nodes, the edge node’s function helps minimize data skewing and performance problems.
