@Indra s: with the S3A connector you can use per-bucket configuration options to set a different username/pass for the remote bucket fs.s3a.bucket.myaccounts3.access.key=AAA12 fs.s3a.bucket.myaccounts3.secret.key=XXXYYY Then when you read or write s3a://myaccounts3/ then these specific username/passwords are used. For other S3A buckets, the default ones are picked up: fs.s3a.access.key=BBBB fs.s3a.secret.key=ZZZZZ Please switch to using the s3a:// connector everywhere: its got much better performance and functionality than the older S3N one, which has recently been removed entirely.
