Updating the Hadoop client configuration files

If you update your Hadoop client configuration files, you can publish your changes to BDD with the bdd-admin script. This distributes the Hadoop client configuration files to all BDD nodes and updates the relevant properties in BDD's configuration files.

When the script runs, it obtains the Hadoop client configuration files from Cloudera Manager/Ambari/MCS, then updates the following:
  • All Hadoop properties in $BDD_HOME/BDD_manager/conf/bdd.conf
  • The following properties in Studio's portal-ext.properties file:
    • dp.settings.hive.metastore.port
    • dp.settings.namenode.port
    • dp.settings.hive.jdbc.port
    • dp.settings.hue.http.port
  • The following properties in Data Processing's edp.properties:
    • hiveServerHost
    • hiveServerPort

When the script finishes running, you must restart your cluster for the changes to take effect.

To update your cluster's Hadoop client configuration files:

  1. On the Admin Server, go to $BDD_HOME/BDD_manager/bin and run: 
    ./bdd-admin.sh publish-config hadoop
  2. Restart your cluster so the changes take effect: 
    ./bdd-admin.sh restart [-t <minutes>]
