In this tutorial I will show you how to kerberize Sqoop installation. Before you begin ensure you have installed Sqoop.
This assumes your hostname is “hadoop”
Create Kerberos Principals
cd /etc/security/keytabs sudo kadmin.local addprinc -randkey sqoop/hadoop@REALM.CA xst -kt sqoop.service.keytab sqoop/hadoop@REALM.CA addprinc -randkey sqoopHTTP/hadoop@REALM.CA xst -kt sqoopHTTP.service.keytab sqoopHTTP/hadoop@REALM.CA q
Set Keytab Permissions/Ownership
sudo chown root:hadoopuser /etc/security/keytabs/* sudo chmod 750 /etc/security/keytabs/*
Configuration
Configure Kerberos with Sqoop
cd /usr/local/sqoop/conf/ nano sqoop.properties #uncomment the following org.apache.sqoop.security.authentication.type=KERBEROS org.apache.sqoop.security.authentication.handler=org.apache.sqoop.security.authentication.KerberosAuthenticationHandler #update to the following org.apache.sqoop.security.authentication.kerberos.principal=sqoop/hadoop@GAUDREAULT_KDC.CA org.apache.sqoop.security.authentication.kerberos.keytab=/etc/security/keytabs/sqoop.service.keytab
