------------------------------------

             Summary: Programmatic configuration of S3 doesn't pass parameters to Hadoop FS
                 Key: FLINK-24595
                 URL: https://issues.apache.org/jira/browse/FLINK-24595
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Hadoop Compatibility
    Affects Versions: 1.14.0
         Environment: Flink 1.14.0

JDK 8 

{{openjdk version "1.8.0_302"}}
{{OpenJDK Runtime Environment (Zulu 8.56.0.23-CA-macos-aarch64) (build 1.8.0_302-b08)}}
{{OpenJDK 64-Bit Server VM (Zulu 8.56.0.23-CA-macos-aarch64) (build 25.302-b08, mixed mode)}}
            Reporter: Pavel Penkov
         Attachments: FlinkApp.java, TickingSource.java, flink_exception.txt

When running in mini-cluster mode Flink apparently doesn't pass S3 configuration to underlying Hadoop FS. With a code like this
{code:java}
Configuration conf = new Configuration();
conf.setString("s3.endpoint", "http://localhost:4566");
conf.setString("s3.aws.credentials.provider","org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider");
conf.setString("s3.access.key", "harvester");
conf.setString("s3.secret.key", "harvester");
StreamExecutionEnvironment env = StreamExecutionEnvironment.createLocalEnvironment(conf);
{code}
Application fails with an exception with most relevant error being {{Caused by: org.apache.hadoop.fs.s3a.auth.NoAuthWithAWSException: No AWS Credentials provided by SimpleAWSCredentialsProvider EnvironmentVariableCredentialsProvider InstanceProfileCredentialsProvider : com.amazonaws.SdkClientException: Failed to connect to service endpoint: }}

So Hadoop lists all the providers but it should use only the one set in configuration. Full project that reproduces this behaviour is available at [https://github.com/PavelPenkov/flink-s3-conf] and relevant files are attached to this issue.
