Generating the BYOS configuration file
The byos.properties
file is used to connect to a DataStax Enterprise cluster from a Spark cluster.
The configuration file contains connection information about the DataStax Enterprise cluster.
This file must be generated on a node in the DataStax Enterprise 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.
Prerequisites
If you are using Graph OLAP queries with BYOS, increase the max_concurrent_sessions
setting in your cluster to 120.
Procedure
-
Connect to a node in your DataStax Enterprise cluster.
-
Generate the
byos.properties
file using thedse client-tool
command.dse client-tool configuration byos-export ~/byos.properties
This generates the
byos.properties
file in your home directory. See Aboutdse client-tool
for more information on the options fordse client-tool
.
What’s next
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 Spark shell on an external Spark cluster.
