I am trying to do some examples with cassandra-cli and encounter the error further below.
Is this really a configuration error ?
If I add key_cache_size_in_mb to the cassandra.yaml file cassandra does not even start.

I have installed Enterprise 2.1 version.

Regards

Cassandra 1.0 does not have key_cache_size_in_mb property. This property was added in 1.1 version.

Cassandra 1.0 cache size was configured per cf. Follow the instructions here:
http://www.datastax.com/docs/1.0/operations/tuning#configuring-the-column-family-key-cache

Sorry for being a dummy.
Why does it complain about the key_cache_size_in_mb?

I do not understand what I should change about the cf either.

The version of DSE (2.1) you are using includes an old version of Cassandra that is not aware of that option.

So if you want to stick with that version, the instructions on how to tweak Cassandra are here: http://www.datastax.com/docs/1.0/operations/tuning#configuring-the-column-family-key-cache.

If you want to change the setting the way you tried (which is consistent with more modern version of Cassandra), I would recommend you go to a newer version of DSE.

Thanks,
Sven

But what is the relation between setting the timeuuid() as :

SET blog_entry['yomama'][timeuuid()] = 'I love my new shoes!';

and the error and the tweaking?
That is what I do not understand.
How do I need to tweak the cache size to prevent the cassandra-cli to terminate?
Is the timeuuid also not permitted in 2.1?

Sorry for the late response. Are you still on this? I would recommend going to a more modern version of DSE, as that has a newer version of C*. I would suspect that as long as you have that option in there, you will see these errors, as the old C* is not supporting that. Does the command work without the change to cassandra.yaml? Do you get a different error?
