This looks the same as or a branch 2.x version of HADOOP-8136. This is something we need to do -it's just I'm too overloaded to do it right now. I'd like to get it into the 2.1-beta2 though

This patch is ready for review. Recommend taking latest(0.9.0) at this point, as 2.X stabilizes.

Hi Steve Loughran, do you know of anyone else who could review?

Overall it looks fine. Do Jets3tNativeS3FileSystemContractTest and Jets3tS3FileSystemContractTest pass with this change? They are live tests run against the real S3 service and are not run by default. You'll need to put S3 credentials into hadoop-common-project/hadoop-common/src/test/resources/core-site.xml to run them.

Nit: catch blocks should be on the same line as the preceding brace.

Hi Tom -

Thanks for the feedback, I will try to scrounge up some time to do the tests and report back the results.

Cheers,
Tim

Canceling in favor of: https://issues.apache.org/jira/browse/HADOOP-9680

Ran into some dependency issues with httpcore with the existing patch. Fixing that and adding some exception handling and logging.

I did the following testing:
1. distcp files of 1G, 5G and 10G
a) hdfs -> s3
b) s3 -> hdfs
2. Teragen to create a 5G file in s3 directly

These were all done from a single node hadoop deployment.

Looks straightforward in general.

Why are these exceptions ignored? Should they be logged? Or could we at least check the exception text before doing this?

The hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/s3/Jets3tFileSystemStore.java file, where you saw those is a piece of the code that's not recommended or used. It's for the S3 interface, not S3N, and there have been conversations about deprecating it (no jira filed yet afaik though). I didn't pay much attention to that code base. Just made sure that no API conflict happened and that it compiled.

Thinking about this more. I'll log the exceptions and do some smoke tests on the s3 connector too. Already done that for the S3N connector. Creating jira for deprecating the S3 connector in a future release.

If there are no alternate suggestions, I think it would be preferable to log these exceptions in Jets3tFileSystemStore.java. We can always change it later if it becomes too verbose.

Let's also make sure that we pay some attention to the (non-S3N) S3 code base as well. It may be removed in the future, but it hasn't been yet.

Incorporating Colin's comments. Did some smoke tests with the s3 interface as well.
