Hi guys. I have a problem using the MapReduce feature of Google App Engine. In general, it works fine, but I am experiencing some strange behaviour in the MapReduce job management. It's just like there are some jobs that are running "zombie" in my application.
So, I got messages like this in the Log: 2012-01-24 11:37:04.599 /mapreduce/mapperCallback 500 1330ms 3kb AppEngine-Google; (+http://code.google.com/appengine) 0.1.0.2 - - [24/Jan/2012:02:37:04 -0800] "POST /mapreduce/ mapperCallback HTTP/1.1" 500 3563 "http://MY_APP_NAME.appspot.com/ mapreduce/mapperCallback" "AppEngine-Google; (+http://code.google.com/ appengine)" "MY_APP_NAME.appspot.com" ms=1331 cpu_ms=895 api_cpu_ms=8 cpm_usd=0.025326 queue_name=default task_name=worker- attempt-1297281267786bca8a816a40a40cdbb5281c37c3c32ef-0001- m-000000-1--3 instance=00c61b117ccd36bf9fca526a2258fa5f3e96 /mapreduce/mapperCallback java.lang.RuntimeException: Couldn't find MR with job ID: job_1297281267786bca8a816a40a40cdbb5281c37c3c32ef_0001 at ... ... ... ... ... and so on. Well, this job id has been executing since November 2011, or even since before. I tried everything: - Delete application - Empty Datastore - Create the application wit other id - Empty the MapReduceState kind - Purge the 'default' task - ... All of this, with no success. There are many people across the forums and lists experiencing the same error, but I haven't found a solution yet. Does anybody know how to get rid of these annoying zombie jobs?? Ikai, where are you when we need your help?? :P If you read this (I hope so), could you erase these jobs manually, or something like that?? Thanks a lot for your help!! Any suggestions will be appreciated. So much. Greetings!! -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
