-----------------------------------
Summary: Sometimes compacted storefiles are archived on region
close
Key: HBASE-20704
URL: https://issues.apache.org/jira/browse/HBASE-20704
Project: HBase
Issue Type: Bug
Components: Compaction
Affects Versions: 2.0.0, 1.4.0, 1.3.0, 3.0.0, 1.5.0
Reporter: Francis Liu
During region close compacted files which have not yet been archived by the
discharger are archived as part of the region closing process. It is important
that these files are wholly archived to insure data consistency. ie a storefile
containing delete tombstones can be archived while older storefiles containing
cells that were supposed to be deleted are left unarchived.
On region close a compacted storefile is skipped from archiving if it has read
references (ie open scanners). This behavior is correct for when the discharger
chore runs but on region close consistency is of course more important so we
should add a special case to ignore any references on the storefile and go
ahead and archive it.
Attached patch contains a unit test that reproduces the problem.
