I know the task tracker frequently kill mappers. During the mapper setup we are kicking off a runtime executable and passing data to and from it within the mapper using unix named pipes. This works OK until a mappers are killed. Currently when this happens the standalone executable is left as a zombie process taking up resources.
Is there any way for my mapper to be notified of the kill and allow it to shutdown the executable before being killed off? A shutdown hook of some kind? Thanks in advance, Sandy
