When you create a Hadoop connection, default values are assigned to cluster environment variables, cluster path properties, and advanced properties. You can add or edit values for these properties. You can also reset to default values.
You can configure the following Hadoop connection properties based on the cluster environment and functionality that you use:
Cluster Environment Variables
Cluster Library Path
Cluster ClassPath
Cluster Executable Path
Common Advanced Properties
Hive Engine Advanced Properties
Blaze Engine Advanced Properties
Spark Engine Advanced Properties
Informatica does not recommend changing these property values before you consult with third-party documentation, Informatica documentation, or Informatica Global Customer Support. If you change a value without knowledge of the property, you might experience performance degradation or other unexpected results.
To reset to default values, delete the property values. For example, if you delete the values of an edited Cluster Library Path property, the value resets to the default $DEFAULT_CLUSTER_LIBRARY_PATH.
