Effective in version 10.2.2, the Data Integration Service can recover a big data job configured to run on the Spark engine when a Data Integration Service node stops unexpectedly. When a Data Integration Service node fails before a job completes, the Data Integration Service sends the job to another node, which resumes processing job tasks from the point at which the node failure occurred.

To recover big data mappings, you must enable big data job recovery in Data Integration Service properties and run the job from infacmd.
