[jira] [Updated] (CASSANDRA-4343) fix sstable blacklisting for LCS
Posted by "Jonathan Ellis (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4343?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Ellis updated CASSANDRA-4343:
--------------------------------------
Attachment: 4343.txt
CompactionsTest failed after CASSANDRA-4341 but the cause was an existing bug in the blacklisting code.
Consider L0 sstables A and B and L1 sstable C. A and B overlap with C, and C is suspect/blacklisted. getCandidatesFor will return {A, B, C}, and getCompactionCandidates will then remove C from the candidate list. A and B will be compacted to D in L1, so L1 will now contain two overlapping sstables C and D.
Patch to fix by check blacklist in getCandidatesFor. If an overlapping sstable is suspect, we'll proceed to the next possible range instead of doing an incorrect compaction. Overlapping suspect sstables in L0 are also handled.
