What happens when an executor is lost? : <p>I get these messages:</p>

<pre><code>16/05/22 13:33:53 ERROR YarnScheduler: Lost executor 61 on &lt;host&gt;: Executor heartbeat timed out after 134828 ms
16/05/22 13:33:53 WARN TaskSetManager: Lost task 25.0 in stage 12.0 (TID 2214, &lt;host&gt;): ExecutorLostFailure (executor 61 lost)
</code></pre>

<p>Will a replacement executor be spawned?</p>
