HDFS configuration
- Port: enter the port of the NameNode of the HDFS (by default, this is 8020)
- Username: enter the username to authenticate in HDFS.
- Timeout: enter the number of milliseconds after which this connection times out with a failure message if it does not receive a response. Enter zero or leave blank to wait indefinitely.
- Use authentication: enable secured connections. If enabled, you need to define the authentication settings:
- Master kerberos principal: Kerberos principal name of the HDFS NameNode as defined and authenticated in the Kerberos Key Distribution Center, typically following the nn/<hostname>@<REALM> pattern.
- Client kerberos principal: Kerberos principal name of a user defined in Kerberos, typically following the <username>/<hostname>@<REALM> pattern.
Keystore: Name of a keystore containing a keytab file with the keys for the user defined in the Client Kerberos principal setting.
Note: The keytab file is present in a readable location in the PRPC server. Examples: /etc/hdfs/conf/thisUser.keytab or c:\authentication\hdfs\conf\thisUser.keytab.
- Test connectivity: test connection to the HDFS NameNode.
