Amazon EMR 7.7.0 - Tez release notes

Amazon EMR 7.7.0 - Tez changes

Type Description
Improvement The tez.task.relaxed.locality property in Apache Tez controls whether task scheduling strictly follows data locality constraints (rack and node locality). When set to true (default in EMR-7.6+), Tez does not enforce locality, allowing tasks to be assigned to any available container, which improves resource utilization and reduces wait times in busy clusters.
