Recovering from 1 of the nodes/slots of a Task Manager failing without resetting entire state during Recovery

I have been going through the book "Real time streaming with Apache Flink". 
How do I recover state for just a single node/slot in a TaskManager without having the recovery reset the application state for all the Task Managers ?

They mention the following:
Reset the state of the whole application to the latest checkpoint, i.e., resetting the state of each task. The JobManager provides the location to the most recent checkpoints of task state. Note that, depending on the topology of the application, certain optimizations are possible and not all tasks need to be reset.

Flink newbie.
