---------------------------
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.
