Release 9.2


Contents:

   

After you have performed the base installation of the  Designer Cloud powered by Trifacta® platform , please complete the following steps if you are integrating with a Hadoop cluster.

If the  Designer Cloud powered by Trifacta platform  is being installed on an edge node of the cluster, you can create a symlink from a local directory to the source cluster files so that they are automatically updated as needed.

  1. Navigate to the following directory on the Trifacta node:

    cd /opt/trifacta/conf/hadoop-site
  2. Create a symlink for each of the Hadoop Client Configuration files referenced in the previous steps. Example:

    ln -s /etc/hadoop/conf/core-site.xml core-site.xml
  3. Repeat the above steps for each of the Hadoop Client Configuration files.

Modify Trifacta configuration changes

  1. To apply this configuration change, login as an administrator to the Trifacta node. Then, edit trifacta-conf.json. For more information, see Platform Configuration Methods.

  2. HDFS: Change the host and port information for HDFS as needed. Please apply the port numbers for your distribution:

    "hdfs.namenode.host": "<namenode>",
    "hdfs.namenode.port": <hdfs_port_num>
    "hdfs.yarn.resourcemanager": {
    "hdfs.yarn.webappPort": 8088,
    "hdfs.yarn.adminPort": 8033,
    "hdfs.yarn.host": "<resourcemanager_host>",
    "hdfs.yarn.port": <resourcemanager_port>,
    "hdfs.yarn.schedulerPort": 8030
  3. Save your changes and restart the platform.
