HBase integration similar to MongoDB river plugin


I am kinda new to both elasticsearch and HBase but for a research project I
would like to combine the two.
My research project mainly involves searching through large portion of
documents (doc,pdf,msg etc) and extracting named entities from the
documents through
mapreduce jobs. Does any one know if there is something similar to MongoDB
river plugin for HBase? Or can point me to some documentation about the
integrating the two?
I have looked on the internet for any documentation but unfortunately
without any luck.

Kind regards,
