> When new RegionScanner, it will add a scanner read point in scannerReadPoints. But if we got a exception after add read point, the read point will keep in regions server and the delete after this mvcc number will never be compacted.
> Our hbase version is base 0.94. If it throws other exception when initialize RegionScanner, the master branch has this bug, too.
