Generate the BYOS configuration file

The byos.properties file is used to connect to a DataStax Enterprise (DSE) cluster from an Apache Spark™ cluster. The configuration file contains connection information about the DSE cluster. This file must be generated on a node in the DSE cluster. You can specify an arbitrary name for the generated configuration file. The byos.properties name is used throughout the documentation to refer to this configuration file.

If you are using Graph OLAP queries with BYOS, increase the max_concurrent_sessions setting in your cluster to 120.
Connect to a node in your DSE cluster.
Generate the byos.properties file using the dse client-tool command:
```
dse client-tool configuration byos-export ~/byos.properties
```
This generates the byos.properties file in your home directory. See Connect an external client to a DataStax Enterprise node with dse client-tool for more information on the options for dse client-tool.
The byos.properties file can be copied to a node in the external Spark cluster and used with the Spark shell, as described in Connecting to DataStax Enterprise using the Apache Spark shell on an external Spark cluster.
