-----------------------------------
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particular compaction event that hasn't been archived yet.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.
