Q:

How to run hadoop application automatically? 

I know that a MapReduce program can be ran using the command line "hadoop jar *.jar" for a time. 
But now the program is required to be ran a time for every hour in background. 
Are there any methods to make the MR program be hourly submitted to hadoop automatically? 
Adding sleeptime(600sec) in program perhaps is working, but it make the app run all the time.
