Nodetool repair validate/preview is not executed

I have 2-nodes test cluster running on Windows machines.

Replication factor: 2
Cassandra version: 3.10

By some reason, nodetool repair command with --validate or --preview flags is not executed at all, looks like parsing error. I'm not quite sure whether it's connected with Windows or I'm doing something wrong. Here's what I get for validate flag (similar results were received for preview flag):

C:\apache-cassandra\bin>nodetool repair --validate
nodetool: Keyspace [--validate] does not exist.

Any ideas how to overcome this error and launch validation before doing repair?

Solution

There is no --validate and --preview option in this version. Thats not until 4.0. The validation repair happens automatically as part of the repair you don't need to specify it. You just cant run it by itself to test the consistency yet.
