> Node refuses to start with
> {code}
> 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.

> org.apache.cassandra.db.ColumnFamilyStore.removeUnfinishedCompactionLeftovers(ColumnFamilyStore.java:544)

> 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.
