HADOOP-BASED HARD DISK DAMAGE HANDLING METHOD AND DEVICE

摘要

Provided are a Hadoop-based hard disk damage handling method and device, the method comprising: information is detected regarding the success of an operation to replace a Hadoop-based damaged hard disk with a replacement hard disk (S202); it is determined whether the replacement hard disk supports data read/write operations (S204); if the result of determining is "yes", then data is read from/written to the replacement hard disk (S206). The above technical solution solves the problem in the related art of handling hard disk damage only by restarting the system, resulting in interrupted services and increased costs; thus the effect of replacing the hard disk is achieved in the case of no system restart and service interruption.
