if disable exception working file

/var/www/magento/lib/zend/cache.php:209

  • just got same exception , believe case belong custom work try make magento working redis-cluster
  • my solution :
    • just remove exception in redis-client.php library first , return ip:port
    • find correct client byhash function in redis-cluster.php
    • execute command correct client
  • need overwrite load , remove , _removebymatchingtags...
