Arun C Murthy commented on MAPREDUCE-3181:
------------------------------------------
Ok, I spent more time on this. I think I finally figured this out.
The reason 'normal' jobs work is that they don't call InputFormat.getSplits
until they create a YARNRunner which, in turn, creates a YarnConfiguration for
the first time. YarnConfiguration has a static block which adds
yarn-(default,site).xml as 'default resources' into the Configuration. Thus any
configuration created after loads these.
The fix afaics is to add yarn-(default,site).xml as default resources in
JobConf via org.apache.hadoop.mapreduce.utilConfigUtil.loadResources the same
time we add mapred-(default,site).xml.
