Patricio Echague commented on CASSANDRA-2386:
---------------------------------------------
The cause of this failure is that
{code} Descriptor.java {code}
{code}
public static Pair<Descriptor,String> fromFilename(File directory, String
name)
{
// name of parent directory is keyspace name
String ksname = directory.getName();
{code}
For a snapshot path like this:
{code}/var/lib/cassandra/data/Keyspace1/snapshots/1307575216104{code}
produces an output: ksname == 1307575216104 (which is wrong).
It should be "Keyspace1"
> sstable2json does not work on snapshot without moving the files

> Moving the *.db files to a folder with the same name as the Keyspace is a
> workaround.
