I had the same issue with DataStax 3.9. This is how I sorted this:
Step 1: Open file: DataStax-DDC\apache-cassandra\conf\cassandra.yaml
Step 2: Uncomment the cdc_raw_directory and set new value to (for windows)
cdc_raw_directory: "C:/Program Files/DataStax-DDC/data/cdc_raw"
Step 3: Goto Windows Services and Start the DataStax DDC Server 3.9.0 Service

I had the same problem with DataStax Community 3.0.9
Step 1: Go to C:\Program Files\DataStax Community\apache-cassandra\conf and open cassandra.yaml in notepad or wordpad
Step 2: Make sure the file has the following entries. If not, add them and save the file.
hints_directory: "C:/Program Files/DataStax Community/data/hints"
data_file_directories: - "C:/Program Files/DataStax Community/data/data"
commitlog_directory: "C:/Program Files/DataStax Community/data/commitlog"
cdc_raw_directory: "C:/Program Files/DataStax Community/data/cdc_raw"
saved_caches_directory: "C:/Program Files/DataStax Community/data/saved_caches"
Step 3: Go to C:\Program Files\DataStax Community\data and make sure you have following folders:
commitlog , data , hints, saved_caches, cdc_raw
If cdc_raw folder is missing, create a folder named cdc_raw
After this, run Cassandra CQL shell again. This should solve the problem.

Goto C:\Program Files\DataStax Community\apache-cassandra\logs\debug.log and find the error.
like I facing was same issue, I checked the logs and there was an error
ERROR [main] 2018-01-16 14:54:49,359 JVMStabilityInspector.java:82 - Exiting due to error while processing commit log during initialization.

i've deleted the the all log files and started server from below location
"C:\Program Files\DataStax Community\apache-cassandra\bin\cassandra.bat"
once your server is up and running now you can open Cassandra CQL Shell

Nothing above worked for me, but this is what did for community 64bit v3.0.9
If you didn't leave "Automatically start DataStax Cassandra Community Service" checked when installing you'll want to reinstall and leave it checked.
Goto C:\Program Files\DataStax Community and rename the file cassandra.ymal.orig to cassandra.yaml and leave it in the DataStax Community folder and start Cassandra CQL Shell.
Note: I don't know if it's needed but I backed up my cassandra.ymal.orig before doing this.
Also, if anyone could shed light on what the command for windows would be to start Cassandra that would be awesome. It seems at least in part this issue is the service just won't start
