Pavel Yaskevich reassigned CASSANDRA-2261: ------------------------------------------ Assignee: Pavel Yaskevich (was: Benjamin Coverston) > During Compaction, Corrupt SSTables with rows that cause failures should be > identified and blacklisted. > ------------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-2261 > URL: https://issues.apache.org/jira/browse/CASSANDRA-2261 > Project: Cassandra > Issue Type: Improvement > Components: Core > Reporter: Benjamin Coverston > Assignee: Pavel Yaskevich > Priority: Minor > Labels: not_a_pony > Fix For: 1.1.1 > > Attachments: 2261-v2.patch, 2261.patch > > > When a compaction of a set of SSTables fails because of corruption it will > continue to try to compact that SSTable causing pending compactions to build > up. > One way to mitigate this problem would be to log the error, then identify the > specific SSTable that caused the failure, subsequently blacklisting that > SSTable and ensuring that it is no longer included in future compactions. For > this we could simply store the problematic SSTable's name in memory. > If it's not possible to identify the SSTable that caused the issue, then > perhaps blacklisting the (ordered) permutation of SSTables to be compacted > together is something that can be done to solve this problem in a more > general case, and avoid issues where two (or more) SSTables have trouble > compacting a particular row. For this option we would probably want to store > the lists of the bad combinations in the system table somewhere s.t. these > can survive a node failure (there have been a few cases where I have seen a > compaction cause a node failure). -- This message is automatically generated by JIRA.
