I want to write a custom interceptor to modify the text of an event (not
just headers). Can this be done? Is there any documentation on how to go
about doing it?

Thanks,

Mark Stern

Hey Mark,

Writing a custom interceptor means writing a Java class that
implements the org.apache.flume.interceptor.Interceptor interface.
Then you include your class in the classpath when launching a flume
agent.

If you look at that interface, you'll see that an interceptor can
modify all of the details of event, including headers and body.

The Javadoc should help a bit, also just look at the stock implementations:
http://flume.apache.org/releases/content/1.2.0/apidocs/org/apache/flume/interceptor/Interceptor.html

The user guide tells you how to put them in your config file:
http://flume.apache.org/FlumeUserGuide.html#flume-interceptors

Mike
