SAS Data Loader uses client Java Archive (JAR) files
and XML client configuration files to connect the client to Hadoop.
Both the JAR and XML files are produced and distributed by Hadoop
vendors such as Cloudera and Hortonworks.
The client JAR files
are obtained from vendors and pre-installed with SAS Data Loader.
At install time, in the SAS Information Center, you select the version
of Hadoop that is implemented on your Hadoop cluster. Your selection
enables the appropriate JAR files. Within the available supported
versions of Hadoop, you can change versions at any time. To change
versions,
see the
next topic Change the Version of Hadoop. New client JAR files for currently
unsupported versions of Hadoop will be delivered in updates to SAS
Data Loader.
The XML client
configuration files are separate from the client JAR files. The XML
files are copied from the Hadoop cluster onto the SAS Data Loader
client during the installation of SAS Data Loader. The XML files are
stored here: vApp-install-path\vApp-instance\SharedFolder\Configuration\HadoopConfig.
