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\$1), 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. |
