Harish Jaiprakash commented on TEZ-4042:
----------------------------------------
Not sure if this is the best strategy. What happens if there is only one node
or yarn keeps giving containers from one node because rest are occupied and it
gets marked as unhealthy? There should be a mechanism built so that it will
fall back and try on the unhealthy node. At the very least please protect it
via a config. So that it can be enabled or disabled.
> Speculative attempts should avoid running on the same node
