The `storageLocation` is the physical location of the fileset. Users can

The value of `storageLocation` depends on the configuration settings of the
catalog:
- If this is a local fileset catalog, the `storageLocation` should be in the
format of `file:///path/to/fileset`.
- If this is a HDFS fileset catalog, the `storageLocation` should be in the
format of `hdfs://namenode:port/path/to/fileset`.
For a `MANAGED` fileset, the storage location is:
-1. The one specified by the user during the fileset creation.
-2. When the catalog property `location` is specified but the schema property
`location` isn't specified,
- the storage location is `catalog location/schema name/fileset name`.
+1. The one specified by the user during the fileset creation, and the
placeholder will be replaced by the
+ corresponding fileset property value.
+2. When the catalog property `location` is specified but the schema property
`location` isn't specified, the storage location is:
+ 1. `catalog location/schema name/fileset name` if `catalog location` does
not contain any placeholder.
+ 2. `catalog location` - placeholders in the catalog location will be
replaced by the corresponding fileset property value.
+
3. When the catalog property `location` isn't specified but the schema
property `location` is specified,
- the storage location is `schema location/fileset name`.
+ the storage location is:
+ 1. `schema location/fileset name` if `schema location` does not contain any
placeholder.
+ 2. `schema location` - placeholders in the schema location will be replaced
by the corresponding fileset property value.

4. When both the catalog property `location` and the schema property
`location` are specified, the storage

5. When both the catalog property `location` and schema property `location`
isn't specified, the user
should specify the `storageLocation` in the fileset creation.
For `EXTERNAL` fileset, users should specify `storageLocation` during the
fileset creation,
