Description

Hi, when this method is called, I see this:

java.lang.NoSuchMethodError: org.yaml.snakeyaml.Yaml.<init>(Lorg/yaml/snakeyaml/constructor/BaseConstructor;)V
at org.apache.cassandra.config.YamlConfigurationLoader.loadConfig(YamlConfigurationLoader.java:86)
at org.apache.cassandra.config.DatabaseDescriptor.loadConfig(DatabaseDescriptor.java:125)
at org.apache.cassandra.config.DatabaseDescriptor.<clinit>(DatabaseDescriptor.java:101)
......

I believe it's because of an enhancement made in ticket CASSANDRA-5606. The version of snakeyaml that 2.0.0-rc1 depends on is 1.6, but this constructor doesn't exist in that version but it does in version 1.12.

Coincidentally CASSANDRA-5317 speaks of upgrading the snakeyaml dependency, but I'm not sure what was upgraded.
