Sylvain Lebresne resolved CASSANDRA-3774.
-----------------------------------------

    Resolution: Duplicate

I don't think you're using current trunk because this was fixed by CASSANDRA-3691.

> this happens in trunk (probably trunk only)
> when changing the compaction strategy to leveled db (via cli), it fails. The C* log shows
an assertion error on org.apache.cassandra.db.DecoratedKey. 
> It looks like it is on key being null, as the LeveledManifest construct it with null:
> {code}
> lastCompactedKeys[i] = new DecoratedKey(cfs.partitioner.getMinimumToken(), null);
> {code}
> The DecoratedKey in 1.0 only check assertion on token. Cassandra-1034 changes the assertion
in trunk to include the key:
> {code}
>     public DecoratedKey(T token, ByteBuffer key)
>     {
>         assert token != null && key != null && key.remaining() > 0;
> {code}
