Example - Cluster Configuration Refresh

Example - Cluster Configuration Refresh

The following example shows the process for importing a property added during a refresh operation after you create it as a user-defined property.
  1. You add the following user-defined property to the cluster configuration:
    <property> <name>runtime.engine.prefix</name> <value>rt_</value> <description>prefixes the runtime output table by this string</description> </property>
  2. The Hadoop administrator adds the property to the cluster, but with a different value, as follows:
    <property> <name>runtime.engine.prefix</name> <value>runtime_</value> <description>prefixes the runtime output table by this string</description> </property>
  3. You refresh the cluster configuration, and the refresh operation performs the following tasks.
    1. Converts the user-defined property to an imported property.
    2. Maintains the user-defined "rt_" value as an overridden value.
    3. Imports the cluster value "runtime_" as the imported value.
