The name of the connection. The name is not case sensitive and must be unique within the domain. You can change this property after you create the connection. The name cannot exceed 128 characters, contain spaces, or contain the following special characters:

~ ` ! $ % ^ & * ( ) - + = { [ } ] | \ : ; " ' < , > . ? /

String that the Data Integration Service uses to identify the connection. The ID is not case sensitive. It must be 255 characters or less and must be unique in the domain. You cannot change this property after you create the connection. Default value is the connection name.

The description of the connection. Enter a string that you can use to identify the connection. The description cannot exceed 4,000 characters.

The name of the cluster configuration associated with the Hadoop environment.

Required if you do not configure the Cloud Provisioning Configuration.

Name of the cloud provisioning configuration associated with a cloud platform such as Amazon AWS or Microsoft Azure.

Required if you do not configure the Cluster Configuration.

Environment variables that the Hadoop cluster uses.

For example, the variable ORACLE_HOME represents the directory where the Oracle database client software is installed.

You can configure run-time properties for the Hadoop environment in the Data Integration Service, the Hadoop connection, and in the mapping. You can override a property configured at a high level by setting the value at a lower level. For example, if you configure a property in the Data Integration Service custom properties, you can override it in the Hadoop connection or in the mapping. The Data Integration Service processes property overrides based on the following priorities:

Mapping custom properties set using
infacmd ms runMapping
with the
-cp
option
Mapping run-time properties for the Hadoop environment
Hadoop connection advanced properties for run-time engines
Hadoop connection advanced general properties, environment variables, and classpaths
Data Integration Service custom properties

The path for shared libraries on the cluster.

The $DEFAULT_CLUSTER_LIBRARY_PATH variable contains a list of default directories.

The classpath to access the Hadoop jar files and the required libraries.

The $DEFAULT_CLUSTER_CLASSPATH variable contains a list of paths to the default jar files and libraries.
