apache pig - Changing the name of Hadoop job? -

-

hi change name of running hadoop job meaningful name. there command change name of running job, -

hadoop job -set-priority <job_id> 'high'; changes priority of job

the job id assigned job tracker on submit, calling jobtracker.getnewjobid(). cannot pre-set. change the job priority, must retrieve id submission. read comments on pig-948 why not possible know mr job id pig:

reason jobcontrolcompiler compiles set of inter-dependent mr jobs , generates job-control object submitted asynchronously hadoop execution. since dont block on thread, possible job-ids not yet assigned when ask them
