Description: The Master Node in a distributed file system cluster is the central component that manages the overall operations of the system. Its primary function is to coordinate tasks among storage nodes, ensuring that data is distributed and synchronized correctly. This node is responsible for managing the cluster configuration, monitoring the status of nodes, and handling data access requests. Additionally, the Master Node facilitates system scalability, allowing for the addition or removal of nodes without interrupting service. In a production environment, its stability and performance are crucial, as any failure in the Master Node can affect the availability of the file system. Therefore, it is recommended to implement high availability strategies to mitigate risks. In summary, the Master Node is essential for the efficient and effective functioning of the distributed file system, acting as the brain of the cluster and ensuring that storage operations are carried out smoothly and in a coordinated manner.
