-------------------------------
Summary: Ability for Tez AM to ignore node updates from YARN
Key: TEZ-2972
URL: https://issues.apache.org/jira/browse/TEZ-2972
Project: Apache Tez
Issue Type: Improvement
Reporter: Jason Lowe
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.
