------------------------------------------
Summary: Make "AUTO" credential provider as default for Kinesis
Connector
Key: FLINK-4611
URL: https://issues.apache.org/jira/browse/FLINK-4611
Project: Flink
Issue Type: Improvement
Components: Kinesis Connector
Reporter: Tzu-Li (Gordon) Tai
Priority: Minor
Fix For: 1.2.0
Right now, the Kinesis Consumer / Producer by default directly expects the
access key id and secret access key to be given in the config properties.
This isn't a good practice for accessing AWS services, and usually Kinesis
users would most likely be running their Flink application in AWS instances
that have embedded credentials that can be access via the default credential
provider chain. Therefore, it makes sense to change the default
{{AWS_CREDENTIALS_PROVIDER}} to {{AUTO}} instead of {{BASIC}}.
To avoid breaking user code, we only use directly supplied AWS credentials if
both access key and secret key is given through {{AWS_ACCESS_KEY}} and
{{AWS_SECRET_KEY}}. Otherwise, the default credential provider chain is used.
