             Summary: Add an "incremental" mode for timeline schema creator
                 Key: YARN-4102
                 URL: https://issues.apache.org/jira/browse/YARN-4102
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Li Lu
            Assignee: Li Lu


When debugging timeline POCs, we may need to create hbase tables that are added 
in some ongoing patches. Right now, our schema creator will exit when it hits 
one existing table. While this is a correct behavior with end users, this 
introduces much trouble in debugging POCs: every time we have to disable all 
existing tables, drop them, run the schema creator to generate all tables, and 
regenerate all test data. 

Maybe we'd like to add an "incremental" mode so that the creator will only 
create non-existing tables? This is pretty handy in deploying our POCs. Of 
course, consistency has to be kept in mind across tables.
