Varun Saxena updated YARN-4053:
-------------------------------
    Description: 
Currently HBase implementation uses GenericObjectMapper to convert and store 
values in backend HBase storage. This converts everything into a string 
representation(ASCII/UTF-8 encoded byte array).
While this is fine in most cases, it does not quite serve our use case for 
metrics. 

So we need to decide how are we going to encode and decode metric values and 
store them in HBase.
