Helping using state storage in Pulsar Functions

[reymor]

Hi everyone,

I'm facing a problem and I am kind of sure that it is a problem related with my configuration. However, I'm not able to figure out what is going wrong.

Version: 2.11.0
Running Pulsar in standalone mode

What I want to do is: Just using Pulsar Functions and using state storage.

I started following Getting started with Pulsar Functions

When I run telnet localhost 4181. I was not able to listen to this port.

After I was looking in different page I found Enable stateful function which seemed to be my problem. However, I got in the same situation.

After just trying to understand different kind of configuration (and there are a lot of different configurations) I am at the point that I'm not really sure if there is something that I need configure.

I just started running individually each component:

1. pulsar zookeer
2. telnet localhost 2181 everything is fine
3. pulsar bookie and here I got this:

Maybe I am missing something. However, maybe due to my expertise in this area. I am not able to see what it is going on. Could you please help me or at least to point out the direction in which I should go? From my point of view, I think that I should be able to follow the guide and use what they show without any problems.

Thanks in advance.
