[ http://issues.apache.org/jira/browse/HADOOP-810?page=comments#action_12457626 ] Arun C Murthy commented on HADOOP-810: --------------------------------------
Runping, could you look at HADOOP-737 & check if HADOOP-639 fixes it for you? Thanks! > The non-existence of the job.xml file causes a LOT of tasks of the job fail > --------------------------------------------------------------------------- > > Key: HADOOP-810 > URL: http://issues.apache.org/jira/browse/HADOOP-810 > Project: Hadoop > Issue Type: Bug > Reporter: Runping Qi > Assigned To: Arun C Murthy > > For some reason, the job.xml file disappears from one of the nodes. That > causes the following exception: > java.lang.RuntimeException: java.lang.RuntimeException: > taskTracker/jobcache/job_0039/job.xml not found > at > org.apache.hadoop.conf.Configuration.loadResource(Configuration.java:551) > at > org.apache.hadoop.conf.Configuration.loadResources(Configuration.java:472) > at org.apache.hadoop.conf.Configuration.getProps(Configuration.java:453) > at org.apache.hadoop.conf.Configuration.get(Configuration.java:201) > at > org.apache.hadoop.conf.Configuration.getBoolean(Configuration.java:286) > at > org.apache.hadoop.mapred.JobConf.getKeepFailedTaskFiles(JobConf.java:212) > at > org.apache.hadoop.mapred.TaskTracker$TaskInProgress.setJobConf(TaskTracker.java:874) > at > org.apache.hadoop.mapred.TaskTracker.launchTaskForJob(TaskTracker.java:313) > at > org.apache.hadoop.mapred.TaskTracker.localizeJob(TaskTracker.java:307) > at > org.apache.hadoop.mapred.TaskTracker.startNewTask(TaskTracker.java:691) > at > org.apache.hadoop.mapred.TaskTracker.checkForNewTasks(TaskTracker.java:533) > at > org.apache.hadoop.mapred.TaskTracker.offerService(TaskTracker.java:448) > at org.apache.hadoop.mapred.TaskTracker.run(TaskTracker.java:720) > at org.apache.hadoop.mapred.TaskTracker.main(TaskTracker.java:1374) > That is fine by itself. > The problem is the task tracker keeps accepting tasks of the same job, and > keeps failing them! > The correct behavior is that it either tries to get the job.xml from the job > tracker, or refuses accepting any new tasks > of the same job. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
