Question(FQDN): how to connect to Pegasus cluster with FQDN pegasus version #2007

Open ninsmiracle opened 1 month ago

General Question

When I deploy master branch of pegasus to real cluster, I could not connect to peagsus via peagsus_shell.

  1. Firstly , I change all the IP to hostname in pegasus config
  2. Then I deloy it to machines
  3. I connected to peagsus cluster via admlin-cli,such as use this command ./admin-cli -n aaa:25101,bbb:25101,but return fatal: failed to list nodes [context deadline exceeded]
  4. I connected to pegasus cluster via pegasus-shell. It works. However,when I type nodes -d ,cluster crash.

stdout(error log) in meta server:

172.17.0.1 is my pegasus-shell IP , which is in a docker. It looks like peagsus can not resolve this IP correctly, it's a bug?

I also fonud these coredump in replica servers.

So I want to know what should I do , to deloy a peagsus cluster with FQDN now , and how to use tools control this cluster. Thanks a lot. @acelyc111

ninsmiracle commented 1 month ago

Let me add more details：

  1. deploy clusters,it works. Every nodes running...

  2. useing peagsus-shell to connected to cluster image

  3. send any RPC command , like nodes -dr or ls -d. TIME_OUT image

4.A lot of core in meta-server image

Core like core.meta.THREAD_PO...

Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `/home/work/app/pegasus/c3tst-performance1/meta/package/bin/pegasus_server confi'.

7.By the way , all the replica-server running during that time image

8.And I can not connect to cluster via admin-cli image

Hi, @ninsmiracle !

Is the Pegasus cluster deployed as a onebox in the docker container? Do the Pegasus shell tool and admin-cli run in the same docker container?

Hi, @ninsmiracle !

When I deloyed as a onebox in my Docker container , cluster run as normal. However, if I deploy it on real node, cluster running but can not accept any RPC.
I think the key point is meta.THREAD_POOL_META_SERVER2.02008e370001000c: rpc_host_port.cpp:62:from_address(): assertion expression: [utils::hostname_from_ip(__bswap_32 (addr.ip()), &hp._host)] invalid host_port 172.17.0.1.

I connected to peagsus cluster via admlin-cli,such as use this command ./admin-cli -n aaa:25101,bbb:25101,but return fatal: failed to list nodes [context deadline exceeded]

It's because after the main FQDN patch has been merged, a new Thrift structure (i.e. host_port) has been introduced, but the admin-cli side dosen't know this type. You can check it in the admin-cli's shell.log, the error looks like:

time="2024-05-23T00:30:55+08:00" level=info msg="failed to read response from [127.0.0.1:34601(meta)]: *admin.ListNodesResponse error reading struct: *admin.NodeInfo error reading struct: Unknown data type 57"

The resolution is to update the admin-cli dependent go-client. However, we have to resolve https://github.com/apache/incubator-pegasus/pull/1917 at first.
