> Project: HBase
> Issue Type: Bug

>
> During object creation "*StoreFileScanner*", it does not increase the
> refCount whereas while close it decrements the reader refCount. This will
> cause refCount to -1 and isReadReference method was returning true
> (refCount.get() != 0 This is causing store file not to be deleted. This may
> also cause issue in situation when some thread is holding a scanner but it
> may actually be closed due to above bug. Impact of this would be really high.
> Attatching patch for the fix which makes sure if reference is held either
> thru getScanner method or constructor, ref is always updated. Patch also
> contains a test which validates the issue.
