Subject [jira] [Created] (HADOOP-13793) s3guard: add inconsistency injection, integration tests
Date Thu, 03 Nov 2016 22:47:00 GMT
Aaron Fabbri created HADOOP-13793:

             Summary: s3guard: add inconsistency injection, integration tests
                 Key: HADOOP-13793
                 URL: https://issues.apache.org/jira/browse/HADOOP-13793
             Project: Hadoop Common
          Issue Type: Sub-task
            Reporter: Aaron Fabbri

Many of us share concerns that testing the consistency features of S3Guard will be difficult
if we depend on the rare and unpredictable occurrence of actual inconsistency in S3 to exercise
those code paths.

I think we should have a mechanism for injecting failure to force exercising of the consistency
codepaths in S3Guard.

- Integration tests that cause S3A to see the types of inconsistency we address with S3Guard.
- These are deterministic integration tests.

Unit tests are possible as well, if we were to stub out the S3Client.  That may be less bang
for the buck, though.
