Cannot change the Credentials Provider

[abhyanka]

In the sample.properties fie, I added a different credentials Provider:
"AWSCredentialsProvider = EnvironmentVariableCredentialsProvider".
I have also set the Environment variable with correct credentials
When I run the consumer, it errors out with ::

java.util.concurrent.ExecutionException: com.amazonaws.AmazonClientException: Unable to load AWS credentials from any provider in the chain
