ccm stress on windows 10 - AuthenticationException

[dins2k2]

Hello,

While trying ccm stress on windows 10, getting the below error. Error seems authentication needs to be provided in the command. But I don't see those stress options. Or do I need to set it up anywhere in any of the config files?

$ ccm node4 stress write n=50000 -rate threads=4

Hello,

I found out the solution.

I have setup Authenticator field as PasswodAuthenticator in cassandra.yaml file. So, stress command throws the above error if you don't provide the username & password like below using -mode option. For more details on stress commands & options, check here.

$ ccm node4 stress write n=10000 cl=one -mode native cql3 user=cassandra password=cassandra

Thanks,
Dinesh
