             Summary: Error reading data from credential file
                 Key: CASSANDRA-19498
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-19498
             Project: Cassandra
          Issue Type: Bug
          Components: Documentation, Tool/cqlsh
            Reporter: Slava


The pylib/cqlshlib/cqlshmain.py code reads data from the credentials file, however, it is immediately ignored.

https://github.com/apache/cassandra/blob/c9625e0102dab66f41d3ef2338c54d499e73a8c5/pylib/cqlshlib/cqlshmain.py#L2070
{code:java}
    if not options.username:
        credentials = configparser.ConfigParser()
        if options.credentials is not None:
            credentials.read(options.credentials)        # use the username from credentials file but fallback to cqlshrc if username is absent from the command line parameters
        options.username = username_from_cqlshrc    if not options.password:
        rawcredentials = configparser.RawConfigParser()
        if options.credentials is not None:
            rawcredentials.read(options.credentials)        # handling password in the same way as username, priority cli > credentials > cqlshrc
        options.password = option_with_default(rawcredentials.get, 'plain_text_auth', 'password', password_from_cqlshrc)
        options.password = password_from_cqlshrc{code}
These corrections have been made in accordance with https://issues.apache.org/jira/browse/CASSANDRA-16983 and https://issues.apache.org/jira/browse/CASSANDRA-16456.

The documentation does not indicate that AuthProviders can be used in the cqlshrc and credentials files.

I propose to return the ability to use the legacy option of specifying the user and password in the credentials file in the [plain_text_auth] section.

It is also required to describe the rules for using the credentials file in the documentation.

I can make a corresponding pull request.
