Zhihong Ted Yu commented on HBASE-5659:
---------------------------------------

Correction for above observation.
Readers for old store files are deleted already (line 1714):
{code}
      // Finally, delete old store files.
      for (StoreFile hsf: compactedFiles) {
        hsf.deleteReader();
      }
{code}
