Matteo Bertozzi commented on HBASE-9926:
----------------------------------------
looks good to me,
It will be nice to have a unit test, if you can reproduce the case with the
MiniCluster.

> Currently the scanner doesn't check if a region is closing/closed. If a
> region is closed, then reopened, an old scanner could still refer to the
> closed HRegion instance. So the scanner will miss some store file changes
> due to compaction.
