--------------------------------
Summary: Add Host-Source input penalties to Unordered Shuffle
Key: TEZ-4005
URL: https://issues.apache.org/jira/browse/TEZ-4005
Project: Apache Tez
Issue Type: Task
Affects Versions: 0.9.1
Reporter: Kuhu Shukla
Ordered shuffle has a mechanism to penalize hosts and try exponential waits for
retrying. Unordered case is missing this feature. Would be really useful to add
this and make shuffle policies consistent.
