CDH install

CDH install

Dear Friends,

 

I could install CDH in 4 node cluster manually so it was good.

 

Now I want to build another cluster and this time I have DNS and LDAP setup.

 

1. Would it be possible to use domain users for installation?

2. The pre-requisite users could they be domain users?

 

Thanks

Re: CDH install

Hi

 

I am trying CDH automatic installation on AWs EC2 using cloudera manager bin. I have created one ubuntu Precise 12.04 LTS micro instance,

 

I followed the on screen instructions as instructions on per this tutorial.. " http://www.cloudera.com/content/cloudera/en/documentation/cloudera-manager/v4-7-1/Cloudera-Manager-I...

 

1) this is my vi /etc/hosts file

127.0.0.1 localhost
172.31.13.46 master

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

 

2) Downloaded and changed the permission for cloudera-manager-installer.bin also.

 

3) sudo ./cloudera-manager-installer.bin after this command cloudera manager installed,

 

4) But i couldnot access cloudera manager webconsole using " http://172.31.13.46:7180 " and i have opened my port 7180 while creating an instance, but still not able to acess through webconsole, 

 

5) my cloudera manager db and cloudera manager server both are running.

 

6) and the port 7180 is also not listning in my ubuntu server and i used the following comand, " sudo ufs allow 7180"  but no use,,

 

7) I checked $ sudo ufw status and the result is inactive

 

8) when I check $ sudo service cloudera-scm-agent status on 172.31.13.46 it comes as unrecognized service

 

 

I am struggling in this part, Could you please let me know where I went wrong in installing cloudera in a clustered environment..???

 

if yes, it will be helpful for me, please,

 

Thanks in advance,

 

Regards,

Bharath

Why do you not use the AWS loop interface for cloudera and set it in your hosts?

 

Did you open the firewall for port 7180?  

 

When I setup Cloudera on AWS or LiNode I use loop interfaces to connect 5 to 10 machines, each system is then configured the same with iptables on loop.

 

I think people might be using the public IP addresses unless you just need console access to public. I usually just for port forward from loop to public interface with ssh keys.
