Hi all,
I am facing issues while executing Junit test cases for my custom processor. 
This is what I have done :


*         I have created my own processor class extended from 
AbstractProcessor.java.

*         For testing I wrote the Junit test class and passed .done file 
location and output directory location to Demux.main()

*         Demux class run and successfully executes my custom processor

*         Convert .done to .evt file in output directory as desired.

Issue : Code of Demux.main() class :

                public static void main(String[] args) throws Exception {
    int res = ToolRunner.run(new Configuration(), new Demux(), args);
    System.exit(res);
                 }

After converting .done file to .evt file , Demux class end the process by 
System.exit() command due to which control is not returned to my JUnit test 
class. Because of this the control is not reaching my assertion and testcase is 
not successful.

Questions

*         I want to know why we have this System.exit() in Demux.java class ?

*         Is there any way I can execute my testcase successfully ? Have any 
one tested processor classes given by chukwa ? Eg : Syslog, TsProcessor etc

*         Since Demux is a daemon which runs continuously . So does everytime 
this demux class is called for every .done file ?


Please Suggest

Thanks
