Francis Liu created HBASE-20724: ----------------------------------- Summary: Sometimes some compacted storefiles are still opened after region failover Key: HBASE-20724 URL: https://issues.apache.org/jira/browse/HBASE-20724 Project: HBase Issue Type: Bug Affects Versions: 2.0.0, 1.4.0, 1.3.0, 3.0.0, 1.5.0 Reporter: Francis Liu
It is important that compacted storefiles of a given compaction execution are wholly opened or 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. When a server fails compaction markers (in the wal edit) are used to determine which storefiles are compacted and should be excluded during region open (during failover). But the WALs containing compaction markers can be prematurely archived even though there are still compacted storefiles for that particular compaction event that hasn't been archived yet. Thus losing compaction information that needs to be replayed. This is because hlog archiving logic only keeps track of flushed storefiles and not archived ones. https://issues.apache.org/jira/browse/HBASE-20704?focusedCommentId=16507680&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16507680 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
