<h2><a name="How_Tez_Uses_YARN_Timeline"></a>How Tez Uses YARN Timeline</h2>
<p>Tez uses YARN Timeline as its application history store. Tez stores most of its lifecycle information into this history store such as: - DAG information such as: - DAG Plan - DAG Submission, Start and End times - DAG Counters - Final status of the DAG and additional diagnostics - Vertex, Task and Task Attempt Information - Start and End times - Counters - Diagnostics</p>
