Example: `hadoop credential create ssl.server.keystore.password jceks://file/tmp/test.jceks` Example: `hadoop credential create ssl.server.keystore.password -provider jceks://file/tmp/test.jceks`
In order to indicate a particular provider type and location, the user must provide the `hadoop.security.credential.provider.path` configuration element in core-site.xml or use the command line option `-provider` on each of the credential management commands. This provider path is a comma-separated list of URLs that indicates the type and location of a list of providers that should be consulted. For example, the following path: `user:///,jceks://file/tmp/test.jceks,jceks://hdfs@nn1.example.com/my/path/test.jceks` indicates that the current user's credentials file should be consulted through the User Provider, that the local file located at `/tmp/test.jceks` is a Java Keystore Provider and that the file located within HDFS at `nn1.example.com/my/path/test.jceks` is also a store for a Java Keystore Provider.
