----------------------------------
Summary: RedisConnectionPoolService doesn't use connection string
in standalone mode
Key: NIFI-5976
URL: https://issues.apache.org/jira/browse/NIFI-5976
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.8.0
Environment: Centos 7
Secured NiFi 2 Node Cluster
Reporter: Josef Zahner
The RedisConnectionPoolService in "Redis Mode - Standalone" doesn't use the
"Connection String". If i insert _myhostname:6379_ it connects to
_localhost:6379_ instead.
*Verified by tcpdump*:
{code:java}
[tester@nifi-03 ~]$ sudo tcpdump -i any -s 1500 -X port 6379 tcpdump: verbose
output suppressed, use -v or -vv for full protocol decode listening on any,

{code}
*Workaround* (ssh tunnel localhost port 6379 to remote host):
{code:java}
ssh -f -C -N -L 127.0.0.1:6379:myhostname:6379 localhost
{code}
