Setting Node Topology with a Script
Provides an overview of how to script setting up node topology.
For large clusters, you can specify complex topologies in a text file or by using a script.
Each line in the text file or script output specifies a single node and the full topology
path for that node in the following format:
<ip or hostname> <topology>
The text file or script must be specified and available on the local filesystem on all CLDB nodes:
- To set topology with a text file, set
net.topology.table.file.name
in/opt/mapr/conf/cldb.conf
to the text file name - To set topology with a script, set
net.topology.script.file.name
in/opt/mapr/conf/cldb.conf
to the script file name
If you specify a script and a text file, the data-fabric system uses the topology specified by the script.
