I am trying to understand if it's possible to run some MR job on the  
response of a custom REST action.

For example, let's say I have a custom REST action that returns a term  
vector of a certain field in the indexed documents. The terms are the  
result of a custom analyzer on a field, say, an entity extractor using the  
elasticsearch-opennlp-plugin. I want this as an input to my Map job. Is  
this possible right now? If not, what are the workarounds?
