<td>
When Spark driver detects an executor termination due to OOM, Spark starts to
allocate the recovery-mode executors which accept only a single task per executor JVM.
In other words, the recovery-mode executors replace the OOM-terminated executors to
survive from the resource-hungry tasks for the remaining tasks and stages.
If set to <code>false</code>, Spark will not use the recovery-mode executors.
