> Major compaction can't work because left scanner read point in RegionServer
> ---------------------------------------------------------------------------

> Key: HBASE-16012
> URL: https://issues.apache.org/jira/browse/HBASE-16012
> Project: HBase
> Issue Type: Bug
> Components: Compaction, Scanners
> Affects Versions: 2.0.0, 0.94.27
> Reporter: Guanghao Zhang
> Fix For: 2.0.0
>
> Attachments: HBASE-16012-v1.patch, HBASE-16012.patch

> 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.
