: <!-- Used to specify an alternate directory to hold all index data
: other than the default ./data under the Solr home.
: If replication is in use, this should match the replication
: configuration
: . -->
: <dataDir>${solr.data.dir:./solr/data}</dataDir>
that directive says "use the solr.data.dir system property to pick a path,
if it is not set, use "./solr/data" (realtive the CWD)
if you want it to use the default, then you need to eliminate it
completley, or you need to change it to the empty string...
<dataDir>${solr.data.dir:}</dataDir>
or...
<dataDir></dataDir>
