Configure the Data Integration Service

Configure the Data Integration Service

When the MapR cluster is secured with Kerberos or MapR Ticket authentication, edit Data Integration Service properties to enable communication between the Informatica domain and the cluster.
In the Administrator tool Domain Navigator, select the Data Integration Service to configure, and then select the
Processes
tab.
In the
Environment Variables
area, configure the following property to define the Kerberos authentication protocol:
Property
Value
JAVA_OPTS
-Dhadoop.login=<MAPR_ECOSYSTEM_LOGIN_OPTS> -Dhttps.protocols=TLSv1.2
where <MAPR_ECOSYSTEM_LOGIN_OPTS> is the value of the MAPR_ECOSYSTEM_LOGIN_OPTS property in the file
/opt/mapr/conf/env.sh
.
MAPR_HOME
MapR client directory on the machine that runs the Data Integration Service.
For example,
opt/mapr
Required if you want to fetch a MapR Streams data object.
MAPR_TICKETFILE_LOCATION
Required when the MapR cluster uses Kerberos or MapR Ticket authentication. Location of the MapR ticket file if you saved it to a directory other than /tmp.
For example:
/export/home/username1/Keytabs_and_krb5conf/Tickets/project1/maprticket_30103
Changes take effect when you restart the Data Integration Service.
