Ambari setup stuck at step 3

avatar

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.

Hi,
I had the same problem as you and I tried to change system locale of /etc/locale.conf from ja_JP.UTF-8 into en_US.UTF-8 and then it works.

Hi, Rahul Narayanan

Have you resolved your problem?

I met the same appearance with you when I was installing Ambari 2.6 on Centos7.1;

my OS information is listing below :

  • CentOS Linux release 7.1.1503 (Core)
  • Linux edgeserver 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

when step 3 was running, I got an error on ambari agent node in file /var/lib/ambari-agent/data/output-107.txt,

2017-12-12 15:05:42,610 - Host checks started. 2017-12-12 15:05:42,610 - Check execute list: last_agent_env_check,installed_packages,existing_repos,transparentHugePage

    return self._lookup_packages(cmd, 'Available Packages')
  File "/usr/lib/python2.6/site-packages/resource_management/core/providers/package/yumrpm.py", line 191, in _lookup_packages
    if items[i + 2].find('@') == 0:
IndexError: list index out of range 2017-12-12 15:05:45,882 - Transparent huge page check started.
2017-12-12 15:05:45,884 - Transparent huge page check completed.
2017-12-12 15:05:45,885 - Host checks completed.

I fixed this issue by modifying code,

'/usr/lib/python2.6/site-packages/resource_management/core/providers/package/yumrpm.py';

original code :

def _lookup_packages(self, command, skip_till):
    """
    :type command list[str]
    :type skip_till str|None
    """
    packages = []
    result = self._call_with_timeout(command)
    if result and 0 == result['retCode']:
      lines = result['out'].split('\n')
      lines = [line.strip() for line in lines]
      items = []
      if skip_till:
        skip_index = 3
        for index in range(len(lines)):
          if skip_till in lines[index]:
            skip_index = index + 1
            break
      else:
        skip_index = 0
      for line in lines[skip_index:]:
        items = items + line.strip(' \t\n\r').split()
      for i in range(0, len(items), 3):
        if '.' in items[i]:
          items[i] = items[i][:items[i].rindex('.')]
        if items[i + 2].find('@') == 0:
          items[i + 2] = items[i + 2][1:]
        packages.append(items[i:i + 3])
    return packages

modified code :

def _lookup_packages(self, command, skip_till):
    """
    :type command list[str]
    :type skip_till str|None
    """
    packages = []
    result = self._call_with_timeout(command)
    if result and 0 == result['retCode']:
      lines = result['out'].split('\n')
      lines = [line.strip() for line in lines]
      items = []
      if skip_till:
        skip_index = 3
        for index in range(len(lines)):
          if skip_till in lines[index]:
            skip_index = index + 1
            break
      else:
        skip_index = 0
      for line in lines[skip_index:]:
        items = items + line.strip(' \t\n\r').split()
      for i in range(0, len(items), 3):
        if '.' in items[i]:
          items[i] = items[i][:items[i].rindex('.')]
        if i + 2 < len(items) :
          if items[i + 2].find('@') == 0:
            items[i + 2] = items[i + 2][1:]
          packages.append(items[i:i + 3])
    return packages

Wish this will be helpful for you!

Thanks!

huan zhou answer worked also on CentOS Linux release 7.5.1804 (Core) (3.10.0-862.3.2.el7.x86_64) with Ambari 2.6.0. It seams that the issue is on yumrpm.py

Hi,

Though this post is old, for the same of future, mentioning my process to solve this issue:

ambari-server reset

remove all the users: Yes

mysql -u root -pwelcome1

show databases;

drop ambari database;

show databases;

quit;

mysql -u ambari -pwelcome1

CREATE DATABASE ambari;

USE ambari;

SOURCE /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql;

show tables;

All the 103 tables will be created.

commit;

quit;

Start Ambari Console and start creating new cluster

At Step 3 following and move ahead Run following script on all nodes:

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent --skip=users

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py --silent

python /usr/lib/python2.6/site-packages/ambari_agent/HostCleanup.py

Uninstall all the unrequired packages

yum remove <package name>

Move ahead
