             Summary: Solr cloud distribute indexing 
                 Key: SOLR-4324
                 URL: https://issues.apache.org/jira/browse/SOLR-4324
             Project: Solr
          Issue Type: Bug
          Components: contrib - DataImportHandler
    Affects Versions: 4.0
         Environment: Red Hat Enterprise Linux Server release 5.3 (Tikanga), Java HotSpot(TM) 64-Bit Server VM (20.0-b11, mixed mode)
            Reporter: Jun Wang


When do full import using DIH, it will delete all segments of all slice by call IndexWriter#deleteAll simultaneously. And deleteAll will call IDF#refresh which removing newly created unreferenced files.

But when IndexWriter#deleteAll is running, solr is add docs to the slice at the same time. So IDF#refresh could delete a segment which is a newly created after call of IDF#refresh before it published to IndexWriter, and after publishFlushedSegment this segment will added to IndexWriter's segmentInfos, and this could cause indexing failed when do IndexWriter#applyAllDeletes or some operation else.
