Description: A node failure refers to an event in which a node within a distributed system becomes inactive or unable to perform its assigned tasks. In the context of distributed data processing systems, a node failure can significantly impact the execution of data processing jobs. Nodes are key components in the architecture, as they are responsible for executing transformations and operations on the data. When a node fails, it can lead to the interruption of the task it was involved in, potentially resulting in data loss or the need to restart processes. To mitigate these issues, distributed systems often implement automatic recovery and task re-scheduling mechanisms, allowing the system to continue functioning even in the presence of failures. Resilience and recovery capability are essential features in distributed systems, and handling node failures is a critical aspect of ensuring the availability and integrity of processed data. In summary, a node failure is an event that can affect the efficiency and effectiveness of data processing systems, and proper management of such failures is fundamental to the success of operations in distributed environments.
