< h1 > MaWo: A Master Worker framework on YARN Services< / h1 > < section >
< h2 > < a name = "Overview" > < / a > Overview< / h2 >
< p > MaWo is a YARN service based framework which handles Master Worker based workload. This is an app which can take an input job specification with tasks, their expected durations and have a Master dish the tasks off to a predetermined set of workers. The components will be responsible to finish the job within specific time duration.< / p > < / section > < section >
