----------------------------------

             Summary: Change the way metric values are stored in HBase Storage
                 Key: YARN-4053
                 URL: https://issues.apache.org/jira/browse/YARN-4053
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Varun Saxena
            Assignee: Varun Saxena


Currently HBase implementation uses GenericObjectMapper is used 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.
