@Abhishek Reddy Chamakura

Could you run these 4 commands on the Ambari server, is there a specific reason that you are installing an old HDP 2.3 version when you have HDP 2.6

# yum erase ambari-server

# yum clean all

# yum repolist

# yum install -y ambari-server

Please revert

Hi Geoffrey,

Thank you for your quick response and time. I ran the below commands and tried setting up amber_server and ran into same issue. Please find attached the steps i did and the error.ambari-server-setup-issue.txt

I am trying to setup a lab environment with similar versions as Production to make a look alike to give another platform to test before deploying to production.

But we are planning to upgrade Ambari from 2.5.0.3 to 2.5.2.0 and HDP to 2.6.1.0.

What is the best way to remove old HDP repos - Do you recommend using yum erase or yum remove ?

Your help is greatly appreciated. Thank you and looking forward to your help.

Thanks,

Abhishek

@Abhishek Reddy Chamakura

Can you tell me the Type and OS version,

I want to quickly reproduce your steps with Ambari 2.5.0.3 and HDP-2.3.4.0 175 can you maybe send the links you used for the downloads.

Hi Geoffrey,

Here are the server details of the virtual machine on which I am trying to install ambari. I also attached the additional processor, memory and disk information.

Node : Virtual Machine

Cores (CPU): 4 (4)Disk:

Memory: 23.46GB

Operating System

$ cat /etc/redhat-release Red Hat Enterprise Linux Server release 6.9 (Santiago)

$ uname -a Linux hdplabambari 2.6.32-696.3.1.el6.x86_64 #1 SMP Thu Apr 20 11:30:02 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux

Just an overview - I requested my Devops team for a 10 node virtual machine all with the close configuration.

This is a new virtual machine and the yum repos that are listed when I type - yum repolist are below. I think the HDP and HDP utils are put in by chef on this node. I didnt download the HDP and HDP utils. I only downloaded the ambari repo.

HDP HDP Version - HDP-2.3.4.0

HDP-UTILS HDP Utils Version - HDP-UTILS-1.1.0.20

ambari ambari-2.5.0.3

To download Ambari Repo i used this Link -

wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.0.3/ambari.repo -O /etc/yum.repos.d/ambari.repo

Please let me konw if i can provide any further info.

FYI - Currently there is nothing on this 10 virtual machines. I am planning to build a Hortonworks Hadoop cluster with this 10 virtual nodes. As part of it i started with the ambari server setup on one node and ran into the above issues. Thank you for all your help.

Thanks,

Abhishek

@Abhishek Reddy Chamakura

I have just completed a single node installation with your current Ambari /HDP versions. All went successfully I have attached the documentation and screenshots of the cluster creation.
Unfortunately, we usually, ignore obvious steps that can cost us time and frustration, please validate my steps against yours. I used the Mysql database and not the embedded Postgres for Ambari, hive, oozie, and ranger backend DB's.

@Abhishek Reddy Chamakura

The installation was successful at the end, so there should be something definitely wrong with either your OS or packages

Enjoy!!!

Hi Geoffrey,

Thank you very much for taking time and testing the installation. I have gone through all of your screenshots. This is what I am planning to do but I am running into issues at the very beginning of the installation of Ambari Server. I will further research into the issue I am running into. Will update you if I find anything.

Thank you very much for your time and fast response.

Have a great weekend!

Thanks

@Abhishek Reddy Chamakura

Can you share the document you are using this cluster install, maybe I could see something that you aint't seeing 🙂 Are you using a satellite server for repos? Can you share the contents of your ambari,hdp and hdp-utils.repos??

I usually don't like to leave an issue un resolved!!

Hi Geoffrey,

Let me give you a little overview on how and where it all started.

Since we have only one Hadoop Cluster which started as a POC and later it was converted to Production environment , we didn't have a lower environment similar to production for testing. So I planned to standup a production like environment with 10 nodes.

I requested for 10 new virtual machines with RHEL 6.9 from devops team at our organization. They provided me 10 new vm's.Brand new vm's with no applications running on it. The devops team did one additional step on the new vm's - enabled chef on the new vm's. Upon the chef-client run it downloaded the below HDP repos , I didn't download the HDP repos neither I used them. I only downloaded ambari repo using the below links

repo id repo name

HDP HDP Version - HDP-2.3.4.0

HDP-UTILS HDP Utils Version - HDP-UTILS-1.1.0.20

Ambari-2.5.0.3 Repo Download Link wget -nv http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.5.0.3/ambari.repo -O /etc/yum.repos.d/ambari.repo

I can stop the chef-client on the new vm's and remove the HDP repos. I want to setup a cluster with Ambari - 2.5.0.3 in the lab environment because currently we are running Ambari - 2.5.0.3 in production. We are planning to upgrade the Ambari version in production. Since I don't have a environment to test the upgrade , I wanted to setup the lab environment with the similar Ambari version in production and ran into ambari-setup issues.

The VM's doesn't have any HDP packages installed or distributed. The VM's are all new and having nothing related to HDP.

Please let me know if you need any further information or a webx session to look into it further.

Thanks
