You need to create a sqoop2.keytab file for Sqoop 2. Follow these steps:

1. Create the principal and keytab file:

   kadmin: addprinc -randkey sqoop2/fully.qualified.domain.name@YOUR-REALM.COM
   kadmin: xst -k sqoop2.keytab sqoop2/fully.qualified.domain.name

2. Move the file into the Sqoop 2 configuration directory and restrict its access exclusively to the sqoop2 user:

   $ mv sqoop2.keytab /etc/sqoop2/conf/
   $ chown sqoop2 /etc/sqoop2/conf/sqoop2.keytab
   $ chmod 400 /etc/sqoop2/conf/sqoop2.keytab

   For more details on creating Kerberos principals and keytabs, see Step 4: Create and Deploy the Kerberos Principals and Keytab Files.

Edit the Sqoop 2 configuration file sqoop.properties file in the /etc/sqoop2/conf directory and add the following properties:

org.apache.sqoop.authentication.type=KERBEROS
org.apache.sqoop.authentication.handler=org.apache.sqoop.security.KerberosAuthenticationHandler
org.apache.sqoop.authentication.kerberos.principal=sqoop2/fully.qualified.domain.name@YOUR-REALM.COM
org.apache.sqoop.authentication.kerberos.keytab=/etc/sqoop2/conf/sqoop2.keytab
