cassandra start failed about clearwater-docker

[johadalin]

Hi there @fogongzi .
I've had a bit of a look at this issue, and at #80. I think the two are likely symptoms of the same underlying error, and i think it's probably that you've got an issue with your etcd pods. Just a heads up: we have a mailinglist for Project Clearwater where you can reach out to the whole community. You may see a quicker response over there, and its good to keep the community up; they may well have hit the same issues before.

Can you confirm that you've got your etcd cluster up and running healthily? Are you following our set up steps from the README? If not, can you give us some more detail on the steps you're following, and how you're deploying all of this?

If your etcd cluster is up and healthy, we can try to work out why your other pods are unable to reach it. If you're on one of your cassandra pods, try taking a look in /var/log/clearwater-cluster-manager/ to see if that has any more informative logs. Similarly in the other issue you've raised, it looks like the configuration files are not being correctly generated, so look in the same logs.

As background here, we have a number of configuration files that are auto-generated based on information that is stored in the etcd cluster. The clearwater cluster manager is the process responsible for getting this information from etcd, and correctly building the configuration up. If your etcd cluster is unhealthy, or unreachable, the other processes wont be able to get the configuration they need to boot up successfully, as you're seeing here.

@johadalin , thank you very much for your reply.
The /var/log/clearwater-cluster-manager/cluster-manager.output.log gives no logs. The /var/log/clearwater-cluster-manager/cluster-manager_20171027T080000Z.txt gives logs as follows:

So what is the problem, I am stucked for few days and can't go on. Thank you very much. I am forwarding to your reply!

@fogongzi
Is that the end of the cluster manager log?
Can you give us a bit more detail on how you're deploying this, and what version of Kubernetes you're deploying on?
Have you made any modifications to the deployment files at all?

I've tried a number of things on my side, and can't get these symptoms to replicate. It might be worth trying a fresh re-deploy, making sure you're using the latest code, and the latest images (rebuilding with the no cached flag set).

[johadalin]

If you attach as much in the way of logs and diagnostics as you can, we should hopefully get to the bottom of it as soon as possible

@johadalin ,yes, It is the end of the cluster log. My environment is as follows:

But it can build succesfully, I can not make sure it is the root cause. Thanks very much, I am forward to your reply!

@fogongzi thanks for providing all that information. Everything looks mostly as i expect it to. I don't believe the errors during the image build are an issue; we should re-vamp the install process to be more container friendly, but i have seen similar and my images are working when deployed.
The only significant difference i can see to what i've run is that you're running Kubernetes 1.80, where my rig is 1.7. I've had a look at the changelog and can't see anything i think would cause the issues you're seeing though.

I think a reasonable next step here would be to re-deploy with 1 of each of Astaire and Cassandra, rather than 3, to see if there is something inherently wrong with the container deployment, or if it's more down to clustering issues.
If you can try the following, and let us know if you have any more success:

• copy your yaml files off to a backup location
• clean your checkout of clearwater-docker and re-generate the yaml files, using the k8s-gencfg script
• change the number of replicas for astaire and cassandra down to 1
• re-deploy using the kubectl apply -f kubernetes/ command

Hopefully the pods will all come up, and reach a healthy state, but if not, we should take a look in the same logs as above. What we would want to find is some reason why the nodes are not progressing to a fully joined state in the cluster, at which point we would create the configuration files for the actual processes to start up with.

@johadalin thank you for your reply. I change the number of replicas for astaire and cassandra down to 1 and the cassandra gives the following error logs:

Therefore, what is the root cause and how can I do. Thanks very much, I am forward to your reply!

[johadalin]

I've had another look over all the diags you've provided, and think i have seen something new regarding the first issue you saw. (I've also added markdown backticks ` around the code/log sections so that it's a bit clearer. Github was parsing the # comments in your depl files as heading tags)

First though, I think the current issue you're seeing with cassandra is down to an issue we've seen with network configuration on the Kubernetes hosts; specifically, cassandra is attempting to bind to the ipv6 loopback interface in the container, but i am guessing it isn't there. The line java.lang.RuntimeException: Unable to create thrift socket to /0:0:0:0:0:0:0:0:9160 shows this.
I'd be interested to see what the interface within the container looks like. If you can run kubectl exec <cassandra pod name> -it /bin/bash, and then grab the output of ifconfig. For comparison, on one of my cassandra pods, i get:

eth0      Link encap:Ethernet  HWaddr 0a:58:0a:e6:11:ec
          inet addr:10.230.17.236  Bcast:0.0.0.0  Mask:255.255.255.0
          inet6 addr: fe80::dc9c:c3ff:fec5:947a/64 Scope:Link

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

          RX packets:31 errors:0 dropped:0 overruns:0 frame:0
          TX packets:31 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1
          RX bytes:3911 (3.9 KB)  TX bytes:3911 (3.9 KB)

We believe this may be resolvable by changing some system config on the host. Particularly, we think ipv6 needs to be enabled, with the sysctl option net.ipv6.conf.all.disable_ipv6 being set to 0. Check your /etc/sysctl.conf file, and make sure this is the case.

Regarding the issue you were having with 3 replicas of each node, the telling line in the cluster manager logs from your cassandra node is: 27-10-2017 00:30:36.473 UTC INFO synchronization_fsm.py:108 (thread CassandraPlugin): Entered state machine for 192.168.0.26 with local state None, cluster state joining, config changing and cluster view {u'192.168.10.21': u'joining, acknowledged change', u'192.168.0.9': u'joining, acknowledged change', u'192.168.4.15': u'joining, acknowledged change'}
Your depl files specified three replicas for cassandra, but from this log we can see that there are four IPs involved in the clustering. I imagine what has happened is the one of the cassandra pods died and was restarted during the clustering process, and the new pod you took the logs from came up in its place. However, because the clustering state machine was mid-way through (all nodes in a joining, acknowledged change state), we are unable to add anything new to the cluster; and because one of the joining nodes no longer exists, the current clustering operation can never complete.

To resolve this, i'd like to check a couple of things:

• Can you make sure you are completely removing all pods completely before creating a new deployment. Running kubectl delete -f kubernetes/ in clearwater docker should work, but make sure all pods are gone before creating new ones
• What command are you using to create a new deployment? If you are hitting clustering issues when using kubectl apply -f kubernetes/, it may be a race condition specific to the conditions on your kubernetes cluster, where nodes come up too slowly or something like that.

Once you have resolved the ipv6 issue, you can go back to attempting to deploy 3 of each of Cassandra and Astaire. If you still hit the clustering issue, i would recommend creating the etcd cluster first, with the etcd depl and svc files, and then once that is up and healthy, creating the cassandra and astaire clusters one at a time. Then you can apply the rest of the depl and svc files to get the full deployment up.

[johadalin]

@fogongzi Hopefully this can resolve your issues and get you up and running 😃

[fogongzi]

@johadalin thank you very much for your reply. The cassandra pod ifconfig command gives :
eth0 Link encap:Ethernet HWaddr 0a:58:c0:a8:09:2b

It seems to be the same as yours.

Next I add net.ipv6.conf.all.disable_ipv6=o to all the kubernetes worker nodes in /etc/sysctl.conf and then execute sysctl -p. I delete all the services and deployment in the clearwater namespace. Then firstly I create deployment etcd and it runs well. Secondly I create deployment astaire and it runs well. Thirdly I runs cassandra, it also gives the following error:

It looks like your pod is still not getting any ipv6 configuration.
You said that the output of ifconfig looked the same as mine, but there's one crucial part missing, which is the ipv6 addresses.
You'll note that the ifconfig output from my cassandra pod contained the following line for eth0:
inet addr:10.230.17.236 Bcast:0.0.0.0 Mask:255.255.255.0
and for the lo inteface:
inet6 addr: ::1/128 Scope:Host

Without any ipv6 configuration on the interfaces, Cassandra is unable to bind the thrift service to 0::0:9160, which is why you're still seeing the log Exception encountered during startup java.lang.RuntimeException: Unable to create thrift socket to /0:0:0:0:0:0:0:0:9160.

Can you confirm that the ipv6 sysctl setting has succeeded? You can check the current sysctl settings for it by running sudo sysctl -a | grep "net.ipv6.conf.all". We believe the disable_ipv6 flag must be set to zero. Also, just to check: In your reply above, you have written that you set "net.ipv6.conf.all.disable_ipv6=o", which is using the letter o, not the digit zero 0. I assume this is a typo, but if not, that may be the source of the problem.

I can not find the key item: inet6 addr: ::1/128 Scope:Host

So what is the problem, my container network is CNI by flanneld. Thank you very much, I am forward to your reply.

Hi @fogongzi , sorry for the delay.
The problem is down to how we're currently setting up our listen addresses in the cassandra yaml, i believe. The line in question i think is https://github.com/Metaswitch/clearwater-cassandra/blob/master/clearwater-cassandra/usr/share/clearwater/cassandra/cassandra.yaml.template#L444 , where we're setting it to ::0. In the past, we used to have this as just 0.0.0.0 but that caused a separate set of issues in different conditions, which is why we changed it.
As it stands now, i don't have time to dig in and come up with the right fix for this, where we probably need to do some more research into the expected container environment.
You should be able to work around this for now though, by building your cassandra container image to replace the rpc_listen_address line. You should be able to do this by modifying the dockerfile to edit the cassandra yaml template. I'd suggest doing some testing with RUN sed -i "s/rpc_address: ::0/rpc_address: 0.0.0.0/" /usr/share/clearwater/cassandra/cassandra.yaml.template at the end of the dockerfile. Hopefully that should get you up and running.

Let me know how it goes

@johadalin Excuse me for jumping in.

I haven't tested enough yet though, this workaround works fine for me.
Do you have any plan to add this command to cassandra/Dockerfile on this repository?
