> RefCnt Leak error when closing a HalfStoreFileReader
> ----------------------------------------------------
>
> Key: HBASE-28893
> URL: https://issues.apache.org/jira/browse/HBASE-28893
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0-beta-1, 2.7.0
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Major
> Fix For: 3.0.0, 2.7.0
>
>
> In HBASE-28596 we have added ability for references to get resolved to the
> original file blocks in bucket cache. As part of this, we had to modify
> HalfStoreFileReader.close method, to create a scanner and seek to boundary
> cell in order to get the related offset and calculate the limiting offset for
> blocks we want to evict. We missed close the scanner instance there, which
> then cause the refcount leaks reported as below:
> {noformat}

> org.apache.hbase.thirdparty.io.netty.util.ResourceLeakDetector: LEAK:
> RefCnt.release() was not called before it's garbage-collected. See
