I have a mapper class (extended from mapreduce.Mapper), where setup reports to an outside resource. I want to make sure that most of the time when the task fails or is killed, a specific chunk of cleanup code is executed.
Just like there's a "setup(Mapper.Context context)" method, there's also a "cleanup(Mapper.Context context)" method for just this purpose.
See: http://hadoop.apache.org/common/docs/r0.20.1/api/org/apache/hadoop/mapreduce/Mapper.html#cleanup(org.apache.hadoop.mapreduce.Mapper.Context)
