stack commented on HBASE-21088:
-------------------------------

Yeah. Seems totally cryptic to me.

Suggest something like this where the close is connected to the location at 
which the files are opened:

{code}
try {
  reloadedStoreFiles = loadStoreFiles();
  return StoreUtils.hasReferences(reloadedStoreFiles);
} finally {
  ..... do close
}
{code}



> HStoreFile should be closed in HStore#hasReferences

> The intention of obtaining the HStoreFile's is to check for references.
> The loaded HStoreFile's should be closed prior to return to prevent leak.
> I noticed the increase in open files when running test suite. After checking 
> recently modified code, I came to this particular method.
