Steve Loughran commented on HADOOP-17500:
-----------------------------------------
ok, start with getting set up to run the hadoop integration test suites, as
documented in:
https://hadoop.apache.org/docs/current/hadoop-aws/tools/hadoop-aws/testing.html
Then see what can be done with adding the building up of the MD5 data. Either
it goes into the S3ABlockOutputStream or we put it into the buffers it builds
up. Putting it in there (S3ADataBlocks) isolates better for unit testing.

> Key: HADOOP-17500
> URL: https://issues.apache.org/jira/browse/HADOOP-17500
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/s3
> Reporter: Pedro Tôrres
> Priority: Major
>
> Hadoop doesn't specify the Content-MD5 of an object when uploading it to an
> S3 Bucket. This prevents uploads to buckets with Object Lock, that require
> the Content-MD5 to be specified.
