Managing the location of Solr data
Controlling where the Solr data files are saved on the server.
Solr has its own set of data files. Like Cassandra data files, you can control where
the Solr data files are saved on the server. By default, the data is saved in
Cassandra data directory/solr.data.
You can change the location from the Cassandra data directory to
another directory, from the command line. For example, on
Linux:
cd install_directory bin/dse cassandra -s -Ddse.solr.data.dir=/opt
In this example, the solr dta is saved in the /opt directory.
