Support Questions

anupshirolkar · ‎08-19-2017

I am setting up a 3 node HDP cluster using Ambari. I have installed ambari server and continuing step wise installation through web UI. I had completed setup till step 9, install,start and test but it was not moving ahead of 32%(see screenshot 2017-08-19.png). So, I restarted the ambari server and now the UI has started from first step again.

Now, I have reached step 3, confirm hosts. The hosts are registered and status is success but The UI is not moving ahead and the message being show is 'Please wait while the hosts are being checked for potential problems...' (see screenshot 2017-08-19-2.png) I tried waiting for a long time but still it doesn't progresses further.

I have also tried restarting ambari agents, restarting ambari server but still same result. These steps I am performing now are already passed once successfully and I haven't changed anything major on the nodes.

Please suggest a solution.

Ambari server log

2017-08-18 11:17:39,720 [CRITICAL] [HIVE] [hive_server_process] (HiveServer2 Process) Connection failed on host hdp25-node2.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net:10000 (Traceback (most recent call last):

Ensure ambari agent is running and the port is is free

(Ambari Agent Heartbeat) hdp25-node1.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net

copy the Ambari,HDP* .repo to /etc/yum.repos.d/ to all other hosts

Confirm the repos are accessible by

# yum repolist

You should see something like this

HDP-2.3.2.0                                       | 2.9 kB     00:00

Updates-ambari-2.1.2.1                            | 2.9 kB     00:00

Check the ambari-agents on these nodes are running if not restart them ensure the value hostname points to your ambari server in the /etc/ambari-agent/conf/ambari-agent.ini

[server] 
hostname={your-ambari-server} 
url_port=8440 
secured_url_port=8441 
hdp25-node1.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net is not sending heartbeats 
hdp25-node2.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net is not sending heartbeats 
hdp25-node3.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net is not sending heartbeats

Error

Caused by: org.apache.ambari.server.HostNotFoundException: Host not found, hostname=

Double check your DNS.

$hostname -f

The output should be FQDN I see a lot of connection refused in the log can you ensure the ambari server can access the other hosts in the cluster

@Geoffrey Shelton Okot

Thanks for bearing with me.

I checked all the configurations as per your suggestion.

1) Ambari-server and agents (all hosts) are running.

2) the repolist have entries as required :

repo id                
!HDP-2.4               
!HDP-UTILS-1.1.0.20    
!Updates-ambari-2.2.2.0

3) /etc/ambari-agent/conf/ambari-agent.ini shows hostname for server (all 3 nodes):

[server]
hostname=hdp25-node1.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net
url_port=8440
secured_url_port=8441

[agent]
prefix=/var/lib/ambari-agent/data
.....

and the hostnames are also correct

[anup@hdp25-node3 ~]$ cat /etc/hosts
127.0.0.1   hdp25-node3.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.4 hdp25-node1.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net
10.0.0.5 hdp25-node2.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net
10.0.0.6 hdp25-node3.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net

I checked the SELinux configuration with `getenforce` and it was permissible so I changed it to `disabled` and rebooted the nodes so that it can take effect.

But, I think this restart has messed up some config of my server. All the setting related to ambari are as given above. But now I cant access the UI like before. I get 'The site cant be find' error.

My setup is based on Microsoft azure, I have tried using the url in different ways (public-ip, hostname)

I have been checking several options like (see from other post)

curl -u admin:admin -i -H 'X-Requested-By: ambari' -X POST -d '{"wizard-data":"{\"userName\":\"admin\",\"controllerName\":\"\"}"}' http://40.121.204.95:8080/api/v1/persist

This one times out.

I dont have any iptables setup. Ambari is show in ps and also 8080 is listening:

[root@hdp25-node1 anup]# service iptables stop
Redirecting to /bin/systemctl stop iptables.service
Failed to stop iptables.service: Unit iptables.service not loaded.

@Anup Shirolkar

Your /etc/hosts entry looks wrong is should look like this you advised never change the first 2 lines for IPV4 and IPV6

127.0.0.1   localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
10.0.0.4 hdp25-node1.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net
10.0.0.5 hdp25-node2.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net
10.0.0.6 hdp25-node3.wulme4ci31tu3lwdofvykqwgkh.bx.internal.cloudapp.net

Can you change that on all the hosts and retry that could be the issue with connection lost !

Why does you repolist output have exclamation marks !!!!!??

!HDP-2.4              
!HDP-UTILS-1.1.0.20    
!Updates-ambari-2.2.2.0

Can you copy /paste the contents of the below files

cat /etc/yum.repos.d/ambari.repo
cat /etc/yum.repos.d/hdp.repo

anupshirolkar · ‎08-20-2017

I did the change in /etc/hosts as per your suggestion. Also the firewall service was restarted due to the VM restart, so I had to turn that down. Now the Ambari UI is connecting.

I have started services and tested few HDFS commands, also Hive commands but, I cannot see YARN resource UI even if the YARN service is up and running. Please suggest solution for that.

About ! in repo names, the RHEL site says it is due to invalid metadata.

@Anup Shirolkar

Good progress can you paste here the screenshot? Now that the first problem was solved I would advice you accept my answer and open a new thread with the YARN UI issue otherwise this thread will be too long to follow.

Thanks

anupshirolkar · ‎08-20-2017

Yes closing this one is a good idea. I have accepted an answer hope that means the thread is closed.

Thanks

Shelton · ‎08-20-2017

Yes open one for the RM/YARN UI people usually ignore a thread that has been there for ages, with long thread.
