Currently there isn’t any support for this in Tez. Expect it to be added soon.

In MapReduce there are parameters for map/reduce tasks in mapred-site.xml. For Hive, it looks like they are similar when running over MapReduce. However, I cannot find anything related to enable speculative execution in tez, or hive for tez. Do you have any idea how I can do that ? Or it is the same "hive.mapred.reduce.tasks.speculative.execution" which works only for reducers.
