Warning

After you define the base storage layer and restart the platform, you cannot change the base storage layer to another option. Please consider your options carefully before you define the base storage layer.

If S3 is the base storage layer, you must also define the default storage bucket to use during initial installation, which cannot be changed at a later time. For additional requirements, see Enable S3 Access.

Info

NOTE: If HDFS is specified as your base storage layer, you cannot publish to Redshift.
