<h1>MaWo: A Master Worker framework on YARN Services</h1><section>
<h2><a name="Overview"></a>Overview</h2>
<p>MaWo is a YARN service based framework which handles Master Worker based workload. This is an app which can take an input job specification with tasks, their expected durations and have a Master dish the tasks off to a predetermined set of workers. The components will be responsible to finish the job within specific time duration.</p></section><section>
<h2><a name="MaWo_Components"></a>MaWo Components</h2>
<p>MaWo app is a YARN Service Application. It has mainly two components.</p>
<ul>
<li>Master</li>
<li>Read MaWo-Payload file and create a queue of Tasks</li>
<li>Register Worker</li>
<li>Assign tasks to worker nodes</li>
<li>Monitor status of Tasks</li>
<li>Log Task status</li>
<li>
<p>Worker</p>
</li>
<li>Send heartbeat to Worker</li>
<li>Execute Task</li>
