    It might be better to link the slave recovery feature in the first sentence to explain
it:
    ```
    Whether to checkpoint task information to disk when running on Mesos, using the Mesos
<a href="http://mesos.apache.org/documentation/latest/slave-recovery/">slave recovery
feature</a>.
    Note: if you use this, Spark will only accept offers from Mesos slaves with checkpointing
enabled.
    ```
