I keep getting this error no matter what the config here is the stacktrace: Stacktrace:

Here is what my config looks like:

require 'redis/namespace'

if Rails.env.production?
  # Using redis-sentinel gem to control sentinel layer
  # https://github.com/mperham/sidekiq/wiki/Advanced-Options
  options = {
    master_name: "master name",
    sentinels: [
      {host: "ip", port: "26379"}, 
      {host: "ip", port: "26379"}, 
      {host: "ip", port: "26379"} #  - arbiter
    ],
    failover_reconnect_timeout: 15, # give 15s for failover to take place
    failover_reconnect_wait: 10 # wait 10s after each failed reconnect
  }

  redis_conn = proc {
    # The following lines use a combination of redis-sentinel and
    # the redis namespace gems to give the connection pool the redis client object
    client = Redis.new(options)
    Redis::Namespace.new("bg_jobs", redis: client)
  }
  Sidekiq.configure_client do |config|
    config.redis = ConnectionPool.new(timeout: 10, size: 5, &redis_conn)
  end
  Sidekiq.configure_server do |config|
    config.redis = ConnectionPool.new(timeout: 10, size: 25, &redis_conn)
  end

else
  port = Rails.env.test? ? "9736" : "6379"
  options = {url: "redis://127.0.0.1:#{port}/12", namespace: "bg_jobs"}
  Sidekiq.configure_server do |config|
    config.redis = options
  end

  Sidekiq.configure_client do |config|
    config.redis = options
  end
end

It of course only happens in production, and I tried doing it all in the console and I get the same errors, however I can get all_clients and for some odd reason it works if I Redis.new().client.current_sentinel.

Any help explaining this would be really appreciated

still trying to figure this out, when I try and set it all up in the console by doing r = Redis.new(options) r.sentinel('sentinels', 'master') fails but r.client.current_sentinel.sentinel('sentinels', 'master') works

when I inspect them r has a wrong port of 6379 when all my sentinels have the port 26379

[tanema]

okay so it turns out it may be a jruby problem. I switched to jruby 1.7.10 (which the project is using) and ran your tests and got the exact same error

[tanema]

moved up to just jruby-1.7.11 and it works. that was not fun.

@tanema I didn't try redis-sentinel in jruby, but I guess it's caused by _parse_sentinel_options, could you try the latest master?
