Before you begin

• •Verify authentication.
• •Verify permissions.
• •Import SSL certificate to the JRE folder of the Informatica Secure Agent.
• •Get Apache Atlas source information.

Verify authentication

• •Add details of the Kerberos server to the host file located in the Secure Agent machine in the following format: <ip_address> <hostname>
On a Windows machine, the host file is available in the following path: C:\Windows\System32\drivers\etc\hosts
On a Linux machine, the host file is available in the following path: /etc/hosts
• •Copy the Atlas Keytab file from the Hadoop cluster to any location on the Secure Agent machine.
• •Enable Atlas hook from Hadoop Distributed File System and Apache Hive configurations so that Apache Atlas can read the metadata.
• • Copy the Kerberos configuration file from the Hadoop cluster to any location on the Secure Agent machine. You can modify the Kerberos configuration file as per requirement.
The following code shows a sample Kerberos configuration file:
[libdefaults]
default_realm = *****
dns_lookup_kdc = false
dns_lookup_realm = false
ticket_lifetime = 86400
renew_lifetime = 604800
forwardable = true
default_tgs_enctypes = rc4-hmac
default_tkt_enctypes = rc4-hmac
permitted_enctypes = rc4-hmac
udp_preference_limit = 1
kdc_timeout = 3000
allow_weak_crypto=true
[realms]
<domain name> = {
kdc = *****
admin_server = *****
}
[domain_realm]
Note: If the Kerberos encryption algorithms are not compatible with Java Standard Edition version 11, you can add the allow_weak_crypto=true property in the Kerberos configuration file.

Verify permissions

• •A user account to access and extract metadata from the Apache Atlas source system.
• •Read permission for the account to access the Apache Atlas source system.
