A good practice to this is to use these two properties in the
core-site.xml, if you will use S3 often:
<property>
     <name>fs.s3.awsAccessKeyId</name>
     <value>AWS_ACCESS_KEY_ID</value>
</property>

<property>
     <name>fs.s3.awsSecretAccessKey</name>
     <value>AWS_SECRET_ACCESS_KEY</value>
</property>

After that, you can access to your URI with a more friendly way:
S3:
  s3://<s3-bucket>/<s3-filepath>

S3n:
  s3n://<s3-bucket>/<s3-filepath>
