> In [SVN 1420992|http://svn.apache.org/viewvc?view=revision&revision=1420992], {{SolrCore#getIndexDir()}} changed it's implementation from a version that would reflect the value of the index property in {{index.properties}} to one that does not.
> In 3.6, {{SolrCore#getIndexDir()}} was:
> {code:java}
> public String getIndexDir() {
> synchronized (searcherLock) {
> if (_searcher == null)
> return dataDir + "index/";
> SolrIndexSearcher searcher = _searcher.get();
> return searcher.getIndexDir() == null ? dataDir + "index/" : searcher.getIndexDir();
> }
> {code}
> In 3.6, {{SolrIndexSearcher}} would be passed the value of {{SolrCore#getNewIndexDir()}} -- which reads index.properties -- in its constructor and return it when {{SolrIndexSearcher#getIndexDir()}} was called.
>
> In 4.1, {{SolrCore#getIndexDir()}} is:
> {code:java}
> public String getIndexDir() {
> return dataDir + "index/";
> }
> {code}
> Clients of {{SolrCore#getIndexDir()}} that were expecting the previous behavior are likely to have issues. E.g.:
> --In {{CoreAdminHandler#handleUnloadAction(SolrQueryRequest, SolrQueryResponse)}} if the {{deleteIndex}} flag is set to true, it calls {{core.getDirectoryFactory().remove(core.getIndexDir())}}. If a value other than {{index/}} is set in {{index.properties}}, the wrong directory will be deleted.
> --In {{CoreAdminHandler#getIndexSize(SolrCore)}}, the existence of {{SolrCore#getIndexDir()}} is checked before {{SolrCore#getNewIndexDir()}}. If a value other than {{index/}} is set in {{index.properties}}, this will return the size of the wrong directory.
