Installation failed – Add nodes step

I can not finalise the installation when I am trying add nodes.
Actually, it failed during installation of ruby-libs.
When I try yum install rubylibs , my system tells me that it requires libreadlines.so.5 even if compat-readline5 is installed !
My system is RHEL 6.

Hi Larry and tedr,

I am using DNS. I can sucessfully ssh to other nodes from the master, and ssh to itself too, obvioussly passwordless.

Hi Fabrice,

Can you successfully ssh from the node on which Ambari is being run to all other nodes in the cluster? Also check that you can ssh from the Ambari machine to itself. All of this ssh’ing must be passwordless.

Thanks,
Ted.

Hi, Fabrice

Thanks for providing the test information.

Are you using /etc/hosts or DNS? If you use /etc/hosts, can you please check if all the hosts in the cluster are in the /etc/hosts on each node?

Hope this helps.

Hi Larry,

I am trying to install one master and three nodes.

I runned the command netstat and I had the following results :


tcp 0 0 0.0.0.0:8441 0.0.0.0:* LISTEN 10434/java
tcp 0 0 10.192.135.146:8441 10.192.135.148:53701 TIME_WAIT -

In the /var/log/ambari-server/ambari-server.log there is a warning :

And in one node /var/log/ambari-agent/ambari-agent.log

Hi, Fabrice

From your log file, I see the following error: Unable to connect to: https://xxxxx:8441/agent/v1/register/xxxx

Can you please also check if your ambari master server is able to connect to https://xxxxx:8441/agent/v1/register/xxxx? Please run the following command on ambari master:
netstat -anp| grep 8441

If there is no record returned from above command, can you please attach the log files from the following directory?

/var/log/ambari-server
/var/log/ambari-agent

Thanks

Larry

Hi Fabrice,

Can you please provide the following information?

1. How many nodes in your cluster?
2. Do you have ssh passwordless set up?
3. What is in the /etc/hosts on each node?
4. What steps you have performed?

Thanks

Larry

HI Fabrice,

Thanks for trying Ambari 1.2. I am looking into the issue you are experiencing.

I have reinstalled with ambari 1.2

Hi Ted,

Yes I have.

[tedrMember]

HI Fabrice,

Thanks for trying HDP.

Have you made sure that the firewall (iptables) is off and SELinux is disabled on all nodes on your cluster?

Thanks!
Ted.

Finally I have succeeded in installing ruby-libs. I think it was a problem of versionning.
But now, when I am trying to configure my cluster, I received a message “Async call failed” at the step “Add Nodes’

[fbvdkaMember]

We did not installed a version of ruby-libs before.
Here the message I received :

Fabrice,
this may be a versioning problem…
HMC trying to install exact version of ruby-libs, and if you have ti installed but on different version, it may fail.
Please, remove your installed package and rerun node addition. This should pull and install expected version.

Thank you!
Sasha
