Prerequisites

Before you begin to work with Cloudera Iceberg as a target in Qlik Replicate, make sure that the following prerequisites have been met:

General
- The WebHDFS NameNode must be accessible from the Qlik Replicate machine.
Clients

Accessing Apache Impala using ODBC requires the following to be installed on the Replicate Server machine:
- Windows: Install ClouderaHiveODBC64_2.9.0 or later.
- Linux: Install ClouderaHiveODBC64_2.9.0 or later.
  
  After the driver is installed, edit the odbcinst.ini file as follows:
  
  [Cloudera ODBC Driver for Impala]
  
  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 Cloudera Iceberg endpoint settings must have write permission for the specified WebHDFS staging directory.
