Suspend and resume a mapreduce job execution

Hi,

I noticed that YARN does not suspend or resume a mapreduce job that it 
is executing. Then, I have found Oozie.

I want to suspend a mapreduce job after all the mappers finish, to 
execute a file check to the output, and then resume the job.

Can I do this with Oozie?


Thanks,

Hi,
I don't see how this can be achieved simply through Oozie XML. However, if you're using Oozie Client Java API and Mapreduce JobClient API, you can submit a job through Oozie -> monitor mapper progress -> and on map progress 100%, issue a command to suspend Oozie job.
