Steve Loughran commented on HADOOP-13060:
-----------------------------------------
I've created HADOOP-13062 to propose using introspection in the 2.7.x branch to
have it link to the newer SDKs.
[~jennydong272]: S3A is very much a community project: whoever uses it gets to
help maintain it. If you could provide the patch for this I'll help nurture it
into the 2.7 branch

> While trying to do a distcp from our native HDFS cluster to S3, we get the

> We are using hadoop-aws.jar version 2.7.1. We are using aws-java-sdk.jar
> version 1.10.69 (we bumped this up from 2.7.4 because we were getting errors
> seen in HADOOP-12420 + other authentication errors).
