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.
