  • I'm voting to close this question as off-topic because Stack Overflow is a [programming-related](http://stackoverflow.com/help/on-topic) Q&A site. Your question is not about programming. Perhaps you should post it on http://magento.stackexchange.com instead? – Enigmativity Mar 18 '16 at 12:11

  • Just got the same exception like you , I believe that case belong to your custom work try to make magento working with redis-cluster
  • My solution :
    • just remove exception in redis-client.php library first and return IP:PORT
    • find the correct client by byHash function in redis-cluster.php
    • execute the command with correct client
  • Need to overwrite load , remove , _removeByMatchingTags...
