             Summary: CoreAdmin - SWAP and RENAME with shared instanceDir and no dataDir - problems after Solr restart
                 Key: SOLR-4732
                 URL: https://issues.apache.org/jira/browse/SOLR-4732
             Project: Solr
          Issue Type: Bug
    Affects Versions: 3.5
            Reporter: Shawn Heisey
             Fix For: 4.3


If your cores share an instanceDir but dataDir is not explicitly defined in solr.xml, apparently dataDir is not "./data" as it would be when instanceDir is not shared, it becomes (or includes) the name of the core as well.  This results in problems problems with RENAME, and probably SWAP as well.  

The RENAME will work, with the dataDir still retaining the old name.  When you restart Solr, however, the core will use the new name for the dataDir and create an empty index, ignoring the old one.  Based on this behavior, I believe that if you did a SWAP, after reload the cores would no longer be swapped.
