Steve Loughran commented on MAPREDUCE-5664:
-------------------------------------------
You need to move up to a recent version of Hadoop: the fixes for your problem
are already in the codebase.
If you can't move up, look at HADOOP-5254 for one route as to how to go about
identifying and working round the XML parser versioning issue *on your own
machine*.
