I am a  developing a spark streaming application dealing with HBase as states of my application.


My user-case need to read from row key,however due to the nature of parallelism of the application..I need to lock the row while I update for a unique row key..when I get the row (using Get object) should not let other thread executor  to read that row-key again until I update the key.This is make me assured my application process the last and valid row ,with updated values.


I actually need locks on my HBase Reads for a particular row key while entering a piece of function.


Can I implement this in  MaprDB and how?
