Embedded Cassandra startup in Scala:

    EmbeddedCassandraServerHelper.startEmbeddedCassandra(
      "/cassandra.yaml",
      60000L
    )

Error:

[info]   org.apache.cassandra.exceptions.ConfigurationException: Expecting URI in variable: [cassandra.config]. Found[file:/C:\examples\target\embeddedCassandra\cassandra.yaml]. Please prefix the file with [file:\\\] for local files and [file:\\<server>\] for remote files. If you are executing this from an external tool, it needs to set Config.setClientMode(true) to avoid loading configuration.

There is no such issue when running cassandra-unit in Linux.
