# tMapROjaiInput

Reads documents from a MapR-DB database to load the data in a given Job.

You must have properly installed and configured your MapR Client before using this component. A \opt\mapr\conf\mapr-clusters.conf file is automatically generated out of the Client configuration process to store the connection information to your MapR cluster and your MapR-DB database. At runtime, this OJAI component reads this connection information by itself to connect to the MapR-DB database to be used.

For further information about how to install and configure your MapR client, see [Setting up the Client](http://doc.mapr.com/display/MapR/Setting+Up+the+Client) from the MapR documentation.
