S3N was a Hadoop filesystem client which can read or write data stored in Amazon S3. It uses URLs with the schema s3n://.
Hadoop’s S3N client for Amazon S3 has been superceded by the S3A connector
Please upgrade to S3A for a supported, higher-performance S3 Client
Keep the hadoop-aws JAR on your classpath.
Add the aws-java-sdk-bundle.jar JAR which Hadoop ships with to your classpath.
Change the authentication keys
| old key | new key |
|---|---|
| fs.s3n.awsAccessKeyId | fs.s3a.access.key |
| fs.s3n.awsSecretAccessKey | fs.s3a.secret.key |
Do make sure the property names are correct. For S3A, they are fs.s3a.access.key and fs.s3a.secret.key —you cannot just copy the S3N properties and replace s3n with s3a.
Replace URLs which began with s3n:// with s3a://
You may now remove the jets3t JAR, as it is no longer needed.
