Hi,
Is preemption only for FAIR ordering policy or can be used for FIFO ordering policy ?
The reason, here why I am asking this question is that we want to use Hive LLAP in our environment. However, to use LLAP, we need to enable 'YARN preemption'. We are using FIFO ordering policies. So, enabling yarn preemption will create any impact even if we are using FIFO ordering policies.
