Li Lu updated YARN-4102: ------------------------ Summary: Add a "skip existing table" mode for timeline schema creator (was: Add an "incremental" mode for timeline schema creator) > Add a "skip existing table" mode for timeline schema creator > ------------------------------------------------------------ > > Key: YARN-4102 > URL: https://issues.apache.org/jira/browse/YARN-4102 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Li Lu > Assignee: Li Lu > Attachments: YARN-4102-YARN-2928.001.patch, > YARN-4102-YARN-2928.002.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
