## Legacy mode ## Supporting older Hadoop version (Legacy jar, BasicOzoneFilesystem)
There are two ozonefs files which includes all the dependencies: There are two ozonefs files, both of them include all the dependencies:

With this method the hadoop-ozone-filesystem-lib-legacy.jar can be used from
any older hadoop version (eg. hadoop 3.1, hadoop 2.7 or spark+hadoop 2.7)
Similar to the dependency jar, there are two OzoneFileSystem implementation.
For hadoop 3.0 and newer, you can use `org.apache.hadoop.fs.ozone.OzoneFileSystem`
which is a full implementation of the Hadoop compatible File System API.
For Hadoop 2.x you should use the Basic version: `org.apache.hadoop.fs.ozone.BasicOzoneFileSystem`.
This is the same implementation but doesn't include the features/dependencies which are added with
Hadoop 3.0. (eg. FS statistics, encryption zones).
### Summary
The following table summarize which jar files and implementation should be used:

Tokens are widely used in Hadoop to achieve lightweight authentication without compromising on security. Main motivation for using tokens inside Ozone is to prevent the unauthorized access while keeping the protocol lightweight and without sharing secret over the wire. Ozone utilizes three types of token: Tokens are widely used in Hadoop to achieve lightweight authentication without compromising on security. Main motivation for using tokens inside Ozone is to prevent the unauthorized access while keeping the protocol lightweight and without sharing secret over the wire. Ozone utilizes three types of token:
#### Delegation token #### #### Delegation token ####
Once client establishes their identity via kerberos they can request a delegation token from OzoneManager. This token can be used by a client to prove its identity until the token expires. Like Hadoop delegation tokens, an Ozone delegation token has 3 important fields: Once client establishes their identity via kerberos they can request a delegation token from OzoneManager. This token can be used by a client to prove its identity until the token expires. Like Hadoop delegation tokens, an Ozone delegation token has 3 important fields:
Renewer: User responsible for renewing the token. 1. **Renewer**: User responsible for renewing the token.
Issue date: Time at which token was issued. 2. **Issue date**: Time at which token was issued.
Max date: Time after which token cant be renewed. 3. **Max date**: Time after which token cant be renewed.
Token operations like get, renew and cancel can only be performed over an Kerberos authenticated connection. Clients can use delegation token to establish connection with OzoneManager and perform any file system/object store related operations like, listing the objects in a bucket or creating a volume etc. Token operations like get, renew and cancel can only be performed over an Kerberos authenticated connection. Clients can use delegation token to establish connection with OzoneManager and perform any file system/object store related operations like, listing the objects in a bucket or creating a volume etc.
#### Block Tokens #### #### Block Tokens ####
Block tokens are similar to delegation tokens in sense that they are signed by OzoneManager. Block tokens are created by OM (OzoneManager) when a client request involves interaction with DataNodes such as read/write Ozone keys. Unlike delegation tokens there is no client API to request block tokens. Instead, they are handed transparently to client along with key/block locations. Block tokens are validated by Datanodes when receiving read/write requests from clients. Block token can't be renewed explicitly by client. Client with expired block token will need to refetch the key/block locations to get new block tokens.

Like block tokens S3Tokens are handled transparently for clients. It is signed by S3secret created by client. S3Gateway creates this token for every s3 client request.

### Certificates ### ### Certificates ###
Apart from kerberos and tokens Ozone utilizes certificate based authentication for Ozone service components. To enable this, SCM (StorageContainerManager) bootstraps itself as an Certificate Authority when security is enabled. This allows all daemons inside Ozone to have an SCM signed certificate. Below is brief descriptions of steps involved: Apart from kerberos and tokens Ozone utilizes certificate based authentication for Ozone service components.

## Authorization ## ## Authorization ##
Ozone provides a pluggable API to control authorization of all client related operations. Default implementation allows every request. Clearly it is not meant for production environments. To configure a more fine grained policy one may configure Ranger plugin for Ozone. Since it is a pluggable module clients can also implement their own custom authorization policy and configure it using [ozone.acl.authorizer.class].

Ozone provides ability to audit all read & write operations to OM, SCM and Datanodes. Ozone audit leverages the Marker feature which enables user to selectively audit only READ or WRITE operations by a simple config change without restarting the service(s). Ozone provides ability to audit all read & write operations to OM, SCM and Datanodes.

Generating audit logs is only half the job, so Ozone also provides AuditParser - a sqllite based command line utility to parse/query audit logs with predefined templates(ex.

Security is not yet implemented, you can *use* any AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY If security is not enabled, you can *use* **any** AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
Note: Ozone has a notion for 'volumes' which is missing from the S3 Rest endpoint. Under the hood S3 bucket names are mapped to Ozone 'volume/bucket' locations (depending on the given authentication information). If security is enabled, you can get the key and the secret with the `ozone s3 getsecret` command (*kerberos based authentication is required).

Now, you can use the key and the secret to access the S3 endpoint:
```
export AWS_ACCESS_KEY_ID=testuser/scm@EXAMPLE.COM
