When deploying Hadoop, what network traffic strategy is recommended?

• A. Segregate cluster and storage network traffic
• B. Combine all traffic into a single network
• C. Use only public IPs for access
• D. Avoid network segmentation for simplicity

Answer: (A)

Segregating cluster and storage network traffic is a recommended strategy when deploying Hadoop because it enhances performance, security, and reliability. In a Hadoop environment, the network is a critical component that handles large volumes of data traffic between nodes in the cluster, as well as between the cluster and storage systems. By keeping cluster communication (such as data replication and task coordination) separate from storage traffic, the system can minimize congestion and potential bottlenecks, leading to better overall performance. Moreover, separating these types of traffic can improve security by limiting access to sensitive data stored within the storage network. It protects the data from unauthorized access that could occur if all traffic is combined over a single network. Additionally, this segregation allows for more efficient use of resources; with dedicated networks, one can apply specific configurations that cater to the unique needs of storage versus cluster communication. For successful Hadoop deployments, it is crucial to ensure that networks are designed with scalability in mind, especially considering the growth of data that big data applications typically encounter. Hence, segregating the network traffic is a best practice that aids in maintaining the efficiency and integrity of the data processing pipeline in Hadoop environments. In contrast, combining all traffic into a single network can lead to increased latency and complications in managing data
