The Hadoop framework provides a mechanism for coping with machine issues such as faulty configuration or impending hardware failure. MapReduce detects that one or a number of machines are performing poorly and starts more copies of a map or reduce task. All the tasks run simultaneously and the task finish first are used.

A. Combine
B. IdentityMapper
C. IdentityReducer
D. Default Partitioner
E. Speculative Execution
