Francis Liu commented on HBASE-20704: ------------------------------------- Uploading exaclty the same file with bumped up rev number to kick of buildbot > Sometimes some compacted storefiles are not 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: 3.0.0, 1.3.0, 1.4.0, 1.5.0, 2.0.0 > Reporter: Francis Liu > Assignee: Francis Liu > Priority: Critical > Fix For: 3.0.0, 2.2.0, 2.1.1, 2.0.3 > > Attachments: HBASE-20704.001.patch, HBASE-20704.002.patch, > HBASE-20704.003.patch, HBASE-20704.004.draft.patch, HBASE-20704.005.patch, > HBASE-20704.006.patch, HBASE-20704.007.patch > > > During region close compacted files which have not yet been archived by the 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 thereby undeleting those cells. > 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 and the > proposed fix. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
