{code} [javac]
C:\Users\mishail\workspace\cassandra\src\java\org\apache\cassandra\db\compaction\CompactionManager.java:810:
error: cannot find symbol
[javac] cfs.clearSnapshot(snapshotName);
[javac] ^
[javac] symbol: method clearSnapshot(String)
[javac] location: variable cfs of type ColumnFamilyStore
{code}
For *getAllKSDirectories*
* {{List<File> snapshotDirs = new ArrayList();}} .It's a raw data type. You
probably meant either {{newArrayList()}} or {{new ArrayList<>()}}
* {{new File(dataDirectory + "/" + ksName)}} and {{File(dataDirectory + "/" +
ksName + "/" + cfDir)}} - you should use
{{org.apache.cassandra.db.Directories.join(String...)}} instead that
concatenation.
* I think it would be better to use one of {{File.listFiles}} methods instead
of {{File.list()}}
> auto_snapshots are not removable via 'nodetool clearsnapshot'

> Snapshots of deleted CFs created via the "auto_snapshot" configuration
> parameter appear to not be tracked. The result is that 'nodetool
> clearsnapshot <keyspace with deleted CFs>' does nothing, and short of
> manually removing the files from the filesystem, deleted CFs remain
> indefinitely taking up space.
> I'm not sure if this is intended, but it seems pretty counter-intuitive. I
> haven't found any documentation that indicates "auto_snapshots" would be
> ignored by 'nodetool clearsnapshot'.
