             Summary: S3Guard testConcurrentTableCreations to set r & w capacity == 1
                 Key: HADOOP-15847
                 URL: https://issues.apache.org/jira/browse/HADOOP-15847
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3, test
    Affects Versions: 3.2.0
            Reporter: Steve Loughran


I just found a {{testConcurrentTableCreations}} DDB table lurking in a region, presumably from an interrupted test. Luckily test/resources/core-site.xml forces the r/w capacity to be 10, but it could still run up bills.

Recommend
* explicitly set capacity = 1 for the test
* and add comments in the testing docs about keeping cost down.

I think we may also want to make this a scale-only test, so it's run less often
