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

Hi guys,



I am wondering how to enable speculative execution when running Hive
queries over Tez.



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.



Thanks,

Robert
