That is excellent question Cheolsoo. Thanks for asking. This property is indeed deprecated on Hadoop 2.0, however is still properly working :-) I've tested it on real Hadoop 2 cluster (based on BigTop 0.4.0).

    Hi Jarcec,
    
    Do we have to worry about Hadoop-2.0.x?
    
    According to Hadoop docs, "mapred.map.tasks.speculative.execution" is depreciated:
    http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/DeprecatedProperties.html
