ramkrishna.s.vasudevan commented on HBASE-15101:
------------------------------------------------
Then you will need to add it in 2 more places. It makes sense to add
close(false) there as anyway there are no more rows there. Does adding close in
those places help you? Am not very sure on that.
> Leaked References to StoreFile.Reader after HBASE-13082

> We observed this production that after a region server dies there are huge
> number of hfiles in that region for the region server running the version
> with HBASE-13082, In the doc it is given that it is expected to happen, but
> we found a one place where scanners are not being closed. If the scanners are
> not closed their references are not decremented and that is leading to the
> issue of huge number of store files not being finalized
> All I was able to find is in the selectScannersFrom, where we discard some of
> the scanners and we are not closing them. I am attaching a patch for that.
> Also to avoid these issues should the files that are done be logged and
> finalized (moved to archive) as a part of region close operation. This will
> solve any leaks that can happen and does not cause any dire consequences?
