Bikas Saha commented on TEZ-2972:
---------------------------------
lgtm. +1.
On the config bit, IMO it could be more direct on the lines of "node unhealthy
reschedule tasks".
Since we setting the default to false, we should mark this jira incompatible.

> This is similar to MAPREDUCE-6119. Sometimes reacting to a node update event
> can cause more harm than good. For example, an UNHEALTHY node may be able to
> shuffle just fine. Therefore obsoleting the output of tasks that ran on that
> node and re-running them simply adds more overhead to the job with no
> benefit. It would be nice to be able to configure Tez to ignore node update
> events if desired.
