Hi, I am trying to implement a new tez task scheduler which tries to allocate tasks uniformly across nodes. As part of this, I am trying to understand how does tez decide which scheduler to use. I could not find any configuration, My current understanding is if its running on yarntez mode, it will use YarnTaskSchedulerService, and if its uber mode it will use LocalTaskSchedulerService. I m interested in using it with hive on tez.
Please let me know what is the configuration for using a new scheduler. Thanks, Dharmesh
