Hi, I run a job which has only one reducer, and through the job tracker page, I saw during the reducer step, it takes a long time (which I think it is normal). but then I saw it has a failure in reducer step when it comes 99% as below:
Task attempt_201207021917_10357_r_000000_0 is over the queue time limit of 900 seconds. Killing! then the reducer automatically restarted, and the second round it succeed. I checked the configuration xml file, it has this: *mapred.queue.default.task-time-limit *900 I guess that is the reason for the first time failure, but I don't understand why the second time it succeeded? Does it automatically adjusted this queue task time limit? Thanks! Sheng
