Abstract
Embodiments of the present invention address deficiencies of the art in respect to distributed computing for large data sets on clusters of computers and provide a novel and non-obvious method, system and computer program product for detecting and correcting malicious nodes in a cloud computing environment (e.g., MapReduce computing). In one embodiment of the invention, a computer-implemented method for detecting and correcting malicious nodes in a cloud computing environment can include selecting a task to dispatch to a first worker node, setting a suspicion index threshold for the selected task, determining a suspicion index for the selected task, comparing the suspicion index to the suspicion index threshold and receiving a result from a first worker node. The method further can include applying a recovery action when the suspicion index exceeds the selected suspicion index threshold.
