Configuring your target processor

You can use the PutHDFS processor to move your data to Ozone, and you can configure the processorto suit your use case.

The following example provides some configurations for PutHDFS. For more information on this Apache NiFi processor, see the Apache NiFi documentation.

Right-click PutHDFS and click Configure Processor.
In the Hadoop Configuration Resources field, specify the Hadoop file system configuration.
The path depends on where your configuration files are located. In this example, /etc/ozone/conf/core-site.xml,/etc/ozone/conf/ozone-site.xml is used.
note

Check /etc/ozone/conf/core-site.xml and make sure fs.defaultFS uses the same protocol as "Directory". For example, ofs://ozone1/ (Recommended), or o3fs://buck1.vol1.ozone1/ (Deprecated).

You can provide a separate set of core-site.xml and ozone-site.xml just for NiFi PutHDFS processors so that the change to "fs.defaultFS" wouldn't affect other components that act as an HCFS client.
Provide your Kerberos credentials.
- Kerberos Principal
- Kerberos Keytab
- Kerberos Password
Set the Directory field to your output directory.
For example: ofs://ozone1/vol1/buck1
note
Ensure to match the protocol used by fs.defaultFS.
Click Apply.

After you have configured your processors, start your dataflow and confirm success.
