             Summary: Improve DynamoDB schema update story
                 Key: HADOOP-14335
                 URL: https://issues.apache.org/jira/browse/HADOOP-14335
             Project: Hadoop Common
          Issue Type: Sub-task
    Affects Versions: HADOOP-13345
            Reporter: Sean Mackrory
            Assignee: Sean Mackrory


On HADOOP-13760 I'm realizing that changes to the DynamoDB schema aren't great 
to deal with. Currently a build of Hadoop is hard-coded to a specific schema 
version. So if you upgrade from one to the next you have to upgrade everything 
(and then update the version in the table - which we don't have a tool or 
document for) before you can keep using S3Guard. We could possibly also make 
the definition of compatibility a bit more flexible, but it's going to be very 
tough to do that without knowing what kind of future schema changes we might 
want ahead of time.
