Ambari setup stuck at step 3

[#1]

Hi,

While installing Ambari 2.6 to setup a 2 node HDP cluster i was stuck at step 3 saying "Please wait while the hosts are being checked for potential problems..". i have checked the ambari-server.log and it says "Unable to lookup the cluster by ID; assuming that there is no cluster and therefore no configs for this execution command: Cluster not found, clusterName=clusterID=-1"

Here is the excerpt from the ambari-server.log

13 Nov 2017 13:09:24,422 WARN [ambari-action-scheduler] ExecutionCommandWrapper:225 - Unable to lookup the cluster by ID; assuming that there is no cluster and therefore no configs for this execution command: Cluster not found, clusterName=clusterID=-1 13 Nov 2017 13:09:25,427 WARN [ambari-action-scheduler] ExecutionCommandWrapper:225 - Unable to lookup the cluster by ID; assuming that there is no cluster and therefore no configs for this execution command: Cluster not found, clusterName=clusterID=-1 13 Nov 2017 13:11:11,433 INFO [pool-18-thread-1] MetricsServiceImpl:65 - Attempting to initialize metrics sink 13 Nov 2017 13:11:11,434 INFO [pool-18-thread-1] MetricsServiceImpl:81 - ********* Configuring Metric Sink ********** 13 Nov 2017 13:11:11,434 INFO [pool-18-thread-1] AmbariMetricSinkImpl:95 - No clusters configured. 13 Nov 2017 13:16:11,434 INFO [pool-18-thread-1] MetricsServiceImpl:65 - Attempting to initialize metrics sink 13 Nov 2017 13:16:11,435 INFO [pool-18-thread-1] MetricsServiceImpl:81 - ********* Configuring Metric Sink ********** 13 Nov 2017 13:16:11,435 INFO [pool-18-thread-1] AmbariMetricSinkImpl:95 - No clusters configured.

Kindly check on your host when you write command $hostname the output exactly matches the fqdn you used specified in repo's.

If not then configure in /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=fqdn

NTPSERVERARGS=iburst

Hope this helps you.

@Rohit Sharma

That was my first step while setting up the cluster

If I type hostname -f

I get xxxxxx.ad.yyyyyy.com

It’s the same that I gave in all my repo file as well

[#4]

@Rohit Sharma

But inside /etc/sysconfig/network

i have only following two

NETWORKING=yes

HOSTNAME=fqdn

i don't have NTPSERVERARGS is it a problem that i have to address

[#5]

@Rahul Narayanan

Use of NTPSERVERARGS=iburst Refer this link hope it helps you

[#6]

@Rahul Narayanan

Can you run the

commands one after the other and proceed with your cluster creation

# ambari-server stop 
# ambari-server reset 
# ambari-server start

Hope that helps
