Hi Gordon,
I double checked that I'm not using any of httpclient/httpcore
or aws-java-sdk-xxx jars in my application.
The only thing I did with aws-java-sdk is to put aws-java-sdk-1.7.4.jar
to /lib described in
https://ci.apache.org/projects/flink/flink-docs-release-1.3/setup/aws.html#flink-for-hadoop-27.
Here's the screenshot of my /lib dir.

Can the root cause be that shaded aws-java-sdk in flink is different
than shaded aws-java-sdk in flink-kinesis-connector?
Thanks!
