Subject Re: Calling a mapreduce job from inside another
Date Sun, 18 Jan 2009 23:51:39 GMT
You can chain job submissions at the client. Also, you can run more than one
job in parallel (if you have enough task slots). An example of chaining jobs
is there in src/examples/org/apache/hadoop/examples/Grep.java where the jobs
grep-search and grep-sort are chained..
