Subject speculative execution in Hive over Tez
Date Mon, 15 Sep 2014 00:25:53 GMT
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
