FAQ
The jobFile is missing from the ApplicationReport, causing at least the MRReliabilityTest job to fail
-----------------------------------------------------------------------------------------------------

Key: MAPREDUCE-2716
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2716
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Jeffrey Naisbitt
Assignee: Jeffrey Naisbitt
Fix For: 0.23.0


The ApplicationReport should have the jobFile (e.g. hdfs://localhost:9000/tmp/hadoop-<USER>/mapred/staging/<USER>/.staging/job_201107121640_0001/job.xml)


Without it, jobs such as MRReliabilityTest fail with the following error (caused by the fact that jobFile is hardcoded to "" in TypeConverter.java):
