Hi Taher,

So you are using the same configuration files and everything and the only thing you change is the "s3://" to "s3a://" and the sink cannot find the credentials?
Could you please provide the logs of the Task Managers?

Cheers,
Kostas

Hi All,
         We have implemented S3 sink in the following way:

StreamingFileSink sink= StreamingFileSink.forBulkFormat(new Path("s3a://mybucket/myfolder/output/"), ParquetAvroWriters.forGenericRecord(schema))
.withBucketCheckInterval(50l).withBucketAssigner(new CustomBucketAssigner()).build();

The problem we are facing is that StreamingFileSink is initializing S3AFileSystem class to write to s3 and is not able to find the s3 credentials to write data, However other flink application on the same cluster use "s3://" paths are able to write data to the same s3 bucket and folders, we are only facing this issue with StreamingFileSink.
