Ramon, If you want to submit with an attached priority, use the APIs [0] and [1] to set the appropriate level before you submit from your JobClient/Job instances.
[0 - New API] - http://hadoop.apache.org/mapreduce/docs/current/api/org/apache/hadoop/mapreduce/Job.html#setPriority(org.apache.hadoop.mapreduce.JobPriority) [1 - Stable API] - http://hadoop.apache.org/mapreduce/docs/current/api/org/apache/hadoop/mapred/JobConf.html#setJobPriority(org.apache.hadoop.mapred.JobPriority) HTH.
