Subject [jira] [Created] (ASTERIXDB-2219) Empty Component Shouldn't be Replicated
Date Wed, 03 Jan 2018 12:59:00 GMT
Murtadha Hubail created ASTERIXDB-2219:
------------------------------------------

             Summary: Empty Component Shouldn't be Replicated
                 Key: ASTERIXDB-2219
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2219
             Project: Apache AsterixDB
          Issue Type: Bug
          Components: STO - Storage
            Reporter: Murtadha Hubail
            Assignee: Murtadha Hubail


When a rollback generates an empty component, it shouldn't trigger replication. Currently
it is replicated and the following exception is encountered:
