-----------------------------------
Summary: Redis Sentinel Database index > 0 connections error in v.
1.14.0
Key: NIFI-9019
URL: https://issues.apache.org/jira/browse/NIFI-9019
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.14.0
Reporter: Jens M Kofoed
After upgrading from v. 1.13.2 to v. 1.14.0 I have issues with Redis connetions
I seems if a RedisConnectionPoolService is configured with a Database Index = 0
there are no issues.
But if I have the Database Index set to 3 I got the following errors in the log:
