Before You Create the Enterprise Data Lake Service
Before You Create the
Enterprise Data Lake Service
Before you create the
Enterprise Data Lake Service
, complete the prerequisite tasks for the service.
Perform the following tasks before you create the
Enterprise Data Lake Service
:
Verify that the Informatica domain has the following services which must be associated with the
Enterprise Data Lake Service
:
Data Integration Service
Model Repository Service
Catalog Service
Content Management Service must be configured if you want to use the data domain discovery feature. Ensure that the database client is installed on all nodes of the Hadoop cluster with the correct settings in the hadoopEnv.properties file.
Data Preparation Service
An
Enterprise Data Lake Service
and a Data Preparation Service must have a one to one association. Do not associate one
Enterprise Data Lake Service
with multiple Data Preparation Service instances, or one Data Preparation Service with multiple
Enterprise Data Lake Service
instances.
If you use HTTPS to connect to the
Enterprise Data Lake Service
, verify the location and password of the keystore and truststore files.
If the domain is secure, you must secure each
Enterprise Data Lake Service
that you create in
Enterprise Data Lake
. The
Enterprise Data Lake Service
instances must use the same keystore and truststore files that the domain uses. If you use separate security certificates, you must add the security certificates for the
Enterprise Data Lake Service
to the truststore and keystore file for the domain. You must use these keystore and truststore files for
Enterprise Data Lake
. You must import the certificate file to the truststore location for the Data Preparation Service and
Enterprise Data Lake Service
.
You must also use the same truststore files for the following services:
Data Integration Service
Model Repository Service
Catalog Service
Data Preparation Service
Enterprise Data Lake Service
If the domain is secure, you must secure the services that you create in
Enterprise Data Lake
.
The following services in the domain and the YARN application must share the same common truststore file:
Data Integration Service
Catalog Service
Data Preparation Service
Enterprise Data Lake Service
You can use different keystore files for the Data Integration Service, Model Repository Service, and Catalog Service. If you use different keystore files, you must add certificates corresponding to each of the keystores into a common truststore file.
The Data Preparation Service and
Enterprise Data Lake Service
must also share the same keystore file.
If you have configured
Enterprise Data Lake
with one primary node and one or more backup nodes, you must copy the truststore files to a common directory and specify the same directory path for all nodes assigned to
