Prerequisites

Before you can use MapR Streams as a target endpoint in a Replicate task, the following prerequisites must be met:

• Install and configure MapR Client 5.2.1 or later on the Qlik Replicate Server machine.

  To verify the configuration, issue the following command in a Linux shell:

  hadoop fs -ls maprfs://<cluster_name>/

  The command should return a directory listing.

• Install the mapr-librdkafka package on the Qlik Replicate Server machine.

• Create a topic named attrep_apply_exceptions before starting the replication task. Note that if this topic does not exist, the task will always fail when it encounters a data error, regardless of the error handling policy.

  For a description of the attrep_apply_exceptions table, see Apply exceptions

• Add the following files to the /opt/attunity/replicate/lib directory:

  • librdkafka.so, libMapRClient_c.so, and libMapRClient.so (copy from the /opt/mapr/lib directory)
  • libjvm.so (copy from the $JAVA_HOME/lib/amd64/server/lib directory)
