if you use default directory then it will use solr.home directory, I have
tested solr cloud example on local machine with 5-6 nodes.And data
directory was created under core name, like
"example2/solr/collection1/data". you could see example startup script from
source code "solr/cloud-dev/solrcloud-multi-start.sh"
example solrconfig.xml
<dataDir>${solr.data.dir:}</dataDir>
