Event Generation

The MapReduce executor can generate events that you can use in an event stream. When you enable event generation, the executor generates events each time it starts a MapReduce job.

MapReduce executor events can be used in any logical way. For example:

With the Email executor to send a custom email after receiving an event.
For an example, see Sending Email During Pipeline Processing.
With a destination to store event information.
For an example, see Preserving an Audit Trail of Events.
