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.

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>

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>

You refresh the cluster configuration, and the refresh operation performs the following tasks.

Converts the user-defined property to an imported property.

Maintains the user-defined "rt_" value as an overridden value.

Imports the cluster value "runtime_" as the imported value.
