Subject [jira] [Comment Edited] (CASSANDRA-6086) Node refuses to start with exception in ColumnFamilyStore.removeUnfinishedCompactionLeftovers when find that some to be removed files are already removed

    [ https://issues.apache.org/jira/browse/CASSANDRA-6086?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13826686#comment-13826686

---------------------------------------------------------------------

Rebased patch against cassandra-2.0 attached.

Again, the patch changes log ERROR and stop starting C* to print WARN but prevent deleting
SSTable if its ancestors are already missing.

> Caused by: java.lang.IllegalStateException: Unfinished compactions reference missing
sstables. This should never happen since compactions are marked finished before we start removing
the old sstables.
>       at org.apache.cassandra.db.ColumnFamilyStore.removeUnfinishedCompactionLeftovers(ColumnFamilyStore.java:544)
>       at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:262)

> IMO, there is no reason to refuse to start discivering files that must be removed are
already removed. It looks like pure bug diagnostic code and mean nothing to operator (nor
he can do anything about this).
> Replaced throw of excepion with dump of diagnostic warning and continue startup.
