Description

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:

[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, link-type LINUX_SLL (Linux cooked), capture size 1500 bytes 13:00:13.422299 IP localhost.52792 > localhost.6379: Flags [S], seq 2959469726, win 43690, options [mss 65495,sackOK,TS val 1907747964 ecr 0,nop,wscale 11], length 0 0x0000: 4500 003c 00e2 4000 4006 3bd8 7f00 0001 E..<..@.@.;..... 0x0010: 7f00 0001 ce38 18eb b065 ec9e 0000 0000 .....8...e...... 0x0020: a002 aaaa fe30 0000 0204 ffd7 0402 080a .....0.......... 0x0030: 71b5 ec7c 0000 0000 0103 030b 0000 0000 q..|............ 0x0040: 0000 0000 0000 0000 0000 0000 ............ 13:00:13.422318 IP localhost.6379 > localhost.52792: Flags [R.], seq 0, ack 2959469727, win 0, length 0 0x0000: 4500 0028 6d71 4000 4006 cf5c 7f00 0001 E..(mq@.@..\.... 0x0010: 7f00 0001 18eb ce38 0000 0000 b065 ec9f .......8.....e.. 0x0020: 5014 0000 2da5 0000 0000 0000 0000 0000 P...-........... 0x0030: 0000 0000 0000 0000

 

Workaround (ssh tunnel localhost port 6379 to remote host):

ssh -f -C -N -L 127.0.0.1:6379:myhostname:6379 localhost
