If you have “cannot parse ‘whatever_my_key’ as hex bytes” when you try to query Cassandra for some data, as in example below:
[code language=”bash”]
[default@CassandraCluster] get ServerLog[‘my_key’] limit 10;
org.apache.cassandra.db.marshal.MarshalException: cannot parse ‘my_key’ as hex bytes
[/code]
then you must set the client-side encoding with assume command:
[code language=”bash”]
[default@CassandraCluster] assume ServerLog keys as utf8;
[/code]
