   > JedisConnectionException: Could not get a resource from the pool
   
   This specific error usually is caused by :
   
   1. smaller number of connections
   2. limited access to redis
   
   To solve it, 
   1. you could enlarge the `druid.cache.maxTotalConnections` and `druid.cache.maxIdleConnections`
   2. check the `druid.cache.password` configuration is correct or if the brokers/historical nodes are in the whitelist of redis
   
   Hope it works
