Todd Lipcon commented on MAPREDUCE-2836: ---------------------------------------- Hi Ahmed. Which branch are you looking at and testing on? The code I see in JobTracker.java is: {code} synchronized (jobs) { synchronized (taskScheduler) { jobs.put(job.getProfile().getJobID(), job); for (JobInProgressListener listener : jobInProgressListeners) { try { listener.jobAdded(job); } catch (IOException ioe) { LOG.warn("Failed to add and so skipping the job : " + job.getJobID() + ". Exception : " + ioe); } } } } {code} which would ignore the error. and in FairScheduler.java: {code} eventLog.log("JOB_ADDED", job.getJobID()); JobInfo info = new JobInfo(new JobSchedulable(FairScheduler.this, job, TaskType.MAP), new JobSchedulable(FairScheduler.this, job, TaskType.REDUCE)); infos.put(job, info); poolMgr.addJob(job); // Also adds job into the right PoolScheduable update(); {code} which would put into infos before calling poolMgr. > Provide option to fail jobs when submitted to non-existent pools. > ----------------------------------------------------------------- > > Key: MAPREDUCE-2836 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-2836 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: contrib/fair-share > Reporter: Jeff Bean > Assignee: Ahmed Radwan > Priority: Minor > Attachments: MAPREDUCE-2836.patch, MAPREDUCE-2836_rev2.patch, > MAPREDUCE-2836_rev3.patch, MAPREDUCE-2836_rev4.patch, > MAPREDUCE-2836_rev5.patch > > > In some environments, it might be desirable to explicitly specify the fair > scheduler pools and to explicitly fail jobs that are not submitted to any of > the pools. > Current behavior of the fair scheduler is to submit jobs to a default pool if > a pool name isn't specified or to create a pool with the new name if the pool > name doesn't already exist. There should be a configuration option for the > fair scheduler that causes it to noisily fail the job if it's submitted to a > pool that isn't pre-specified or if the specified pool doesn't exist. -- This message is automatically generated by JIRA.
