Cassandra on Windows: Fatal configuration error

Question

We installed Cassandra 2.0.6 in Windows 7 with JRE 7 and we updated the cassandra.yaml file as shown:

data_file_directories: D:\cassandra_data\data
commitlog_directory: D:\cassandra_data\commitlog
saved_caches_directory: D:\cassandra_data\saved_caches

When we are trying to start cassandra server (D:\cassabdra\bin\cassandra.bat) we are getting following error

Starting Cassandra Server
INFO 13:19:39,272 Logging initialized
INFO 13:19:39,299 Loading settings from file:/D:/cassandra/conf/cassandra.yaml

You should use forward slashes (/), even on Windows:

In you case, it would be:

data_file_directories: 
    - "D:/cassandra_data/data" 
commitlog_directory: "D:/cassandra_data/commitlog" 
saved_caches_directory: "D:/cassandra_data/saved_caches"
