Possible Postgres Version Causing Ambari Server Setup Problems

The version of Postgres that is installed with Ambari is different than what is listed in the documentation. I continue to encounter an error about being unable to start the Postgres server. Is this possibly related to the versions being different (detail below)?

[root@ip-10-253-6-179 ~]# ambari-server setup
Using python /usr/bin/python2.6
Run postgresql initdb
postgresql: unrecognized service
Run postgresql start
postgresql: unrecognized service
Setup ambari-server
Checking SELinux…
WARNING: Could not run /usr/sbin/sestatus: OK
Checking iptables…
iptables is disabled now
Checking PostgreSQL…
About to start PostgreSQL
ERROR: Unable to start PostgreSQL server. Exiting

There are not log files in the Ambar log file directory. I FTPed the output from check.

To simplify, I am now just trying to install on a one-node cluster.
When I yum install -y ambari-server, these versions of the postgres components install:

[root@ip-10-253-6-179 ~]# rpm -qa | grep -ie postgres*
postgresql91-server-9.1.5-3PGDG.rhel6.x86_64
postgresql91-9.1.5-3PGDG.rhel6.x86_64
postgresql91-libs-9.1.5-3PGDG.rhel6.x86_64

The versions necessary for Ambari and HDP to run are listed here and are different than what was installed:

http://docs.hortonworks.com/HDPDocuments/HDP1/HDP-1.2.1/bk_using_Ambari_book/content/ambari-chap1-5-1.html

listed at this above URL are:
postgresql 8.4.13-1.el6_3
postgresql-libs 8.4.13-1.el6_3
postgresql-server 8.4.13-1.el6_3

I’m on an AWS instance, here is the CentOS version, [root@ip-10-253-6-179 ~]# cat /etc/*-release
CentOS release 6.3 (Final)
CentOS release 6.3 (Final)
CentOS release 6.3 (Final)

The AMI is: ami-2ac9411a

Hello,

I am having the same problem. Grr! I did yum install postgres etc. But problem still exist:

Starting postgresql service: [FAILED]

Any ideas what could be wrong ? I am following guide found on Hortons webpage.

Hi Phillip,

Thanks for the information. I am informed by our Eng folks that we don’t specify which version of postgresql to dl, we just have a requirement that it be greater than 8. Apparently, from your experience, it also must be less than 9.1. I will log an issue on the Ambari Jira.

Thanks,
Ted.

Hi, Ted. The OS version is CentOS 6.3. Here is information from the AWS AMI:

RightImage_CentOS_6.3_x64_v5.8.8.5 (ami-2ac9411a)

Hi Phillip,

Thanks for letting us know. We’ll look into how it was that 9.1.5 was installed and how to make sure that the correct version get’s installed. To help us with this could you tell us what is the OS and version you are running on?

Thanks,
Ted.

I solved this. I installed Postgres 8.4.13 using this command:

yum install postgresql postgresql-server

Ambari server started up after this.

postgres 9.1.5 was definitely installed with Ambari server.
