Before you begin to work with CDP Private Cloud as a target in Qlik Replicate, make sure that the following prerequisites have been met:
-
General:
- The HDFS storage must be accessible from the Qlik Replicate machine.
- When ODBC Access is selected, the Hive Server must be accessible from the Qlik Replicate machine.

ODBC Access:
Accessing Hive using ODBC requires the following to be installed on the Replicate Server machine:
-
Windows: Install Cloudera ODBC driver for Apache Hive 2.6.9 or later.
-

Before you can use SSL, you first need to perform the following tasks:
- Configure each NameNode and each DataNode with an SSL certificate (issued by the same CA).
- Place the CA certificate on the Replicate Server machine. The certificate should be a base64-encoded PEM (OpenSSL) file.
-
Permissions:
The user specified in the CDP Private Cloud target settings must have write permission for the specified HDFS target directory.

Task Settings:
Before starting a task with the Full Load and/or Apply Changes replication options enabled, set the Change Processing Mode to Transactional apply as Batch optimized apply is not supported.
