             Summary: RedisConnectionPoolService does not work with Standalone Redis using non-localhost deployment
                 Key: NIFI-5830
                 URL: https://issues.apache.org/jira/browse/NIFI-5830
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.8.0
         Environment: Ubuntu 16 LTS, NiFi 1.8.0
            Reporter: Alexander Bukarev


The controller service {{RedisConnectionPoolService}} does not work with Standalone Redis which is deployed on a host other than {{localhost}} (or if Redis uses the port other than {{6379}}). So the only way to use {{RedisConnectionPoolService}} is to deploy Redis on {{localhost}} and run it with default port {{6379}}.

*Steps*:
Let's assume our Redis is deployed on host *redis* (not {{localhost}}) and it listens port 6379 (I use docker for that)
# Create a {{PutDistributedMapCache}} processor
# Configure the processor with {{RedisDistributedMapCacheClientService}} 
# Create a new controller service: {{RedisConnectionPoolService}}
#* Choose *Standalone* Redis Mode
#* Use *redis:6379* as a Connection String
# Connect some incoming flow to the {{PutDistributedMapCache}} processor (I've used {{GetFile}} as a producer) and run the whole flow. Allow {{GetFile}} to consume some file (if you use {{GetFile}} ro reproduce) and wait some time till the {{PutDistributedMapCache}} will be schedulled.

Result:
The processor is failed to run. And we can see the error in logs:
