Guanghao Zhang created HBASE-16012:
--------------------------------------
Summary: 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: 0.94.27, 2.0.0
Reporter: Guanghao Zhang
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.
