Using elasticsearch-hadoop, I'd like to write a map reduce job where the  
EsOutputFormat writes both child and parent documents. However, it appears  
that it can only write parent or child documents within a single job. To  
write child documents, one needs to set the "es.mapping.parent" property in  
the JobConf, which I believe then messes up writing of the parent  
documents, which obviously don't have a parent. Is there a way to work  
around this?
