Prerequisites

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.
- Linux: Install Cloudera ODBC driver for Apache Hive 2.6.9 or later.
  
  After the driver is installed, edit the odbcinst.ini file as follows:
  
  DriverManagerEncoding=UTF-16
  
  ODBCInstLib=libodbcinst.so
SSL:

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.
