Hi, when I give only hosts and port, I get :

root@master:/# cassandra-web --hosts '192.168.10.134' --port '9042'
TypeError: can't convert nil into Integer

Usage: cassandra-web [options]

    -P, --port PORT                  integer port that cassandra is running on (default: 9042)

ArgumentError: :username must be a String, nil given

Hmm, I'm not sure what's going on, can you try without single quotes?

The same:

root@master:/# cassandra-web -H 192.168.10.134 -P 9042
TypeError: can't convert nil into Integer

Usage: cassandra-web [options]
    -B, --bind BIND                  ip:port or path for cassandra web to bind on (default: 0.0.0.0:3000)
    -H, --hosts HOSTS                coma-separated list of cassandra hosts (default: 127.0.0.1)
    -P, --port PORT                  integer port that cassandra is running on (default: 9042)
    -L, --log-level LEVEL            log level (default: info)
    -u, --username USER              username to use when connecting to cassandra
    -p, --password PASS              password to use when connecting to cassandra
    -C, --compression NAME           compression algorithm to use (lz4 or snappy)
        --server-cert PATH           server ceritificate pathname
        --client-cert PATH           client ceritificate pathname

        --passphrase SECRET          passphrase for the private key
    -h, --help                       Show help

By the way, I test cassandra-web on docker . Click here for dockerfile.

Hi, same behaviour here, but with username parameter...

ArgumentError: :username must be a String, nil given

Options passed to Cassandra Driver seems to not get resolved correctly.
Snippet from driver source code where it fails:

username = options.delete(:username)
password = options.delete(:password)

Util.assert_instance_of(::String, username) do
  ":username must be a String, #{username.inspect} given"
end
Util.assert_instance_of(::String, password) do
  ":password must be a String, #{password.inspect} given"
end

something is up with option parsing, I'd appreciate your help debugging.

I tested the app as it stands today the option parsing does indeed work. I would make a note that c* host has to be an IP and not a host name else the app breaks it seems.
