I am running 2 separate 4.3 SolrCloud clusters. On one of them I noticed the file data/index.properties on the replica nodes where the index directory is named "index.<value of index property in index.properties>". On the other cluster, the index directory is just named "index".
Under what condition is index.properties created? I am trying to understand why there is a difference between my 2 SolrCloud clusters. Bill
