[SOLVED] Error: cannot find which cluster host is the local host.

ismael_vc

Hello everyone!

 

I've been trying recently to install Vertica on a 20 node CentOS 6 cluster, I have installed the dependencies (in this case only the package dialog), after that I run on the master node:

 

 

 rpm -Uvh vertica-7.2.0-0.x86_64.RHEL6.rpm

And it finishes successfuly, but after that when I try to run:

 

 

[root@hd0 ~]# /opt/vertica/sbin/install_vertica --hosts hd1,hd2,hd3,hd4,hd5,hd6,hd7,hd8,hd9,hd10,hd11,hd12,hd13,hd14,hd15,hd16,hd17,hd18,hd19

I get into this problem and I haven't been able to figure it out yet (example output):

 

[root@hd0 ~]# /opt/vertica/sbin/install_vertica --hosts hd1,hd2,hd3,hd4,hd5,hd6,hd7,hd8,hd9,hd10,hd11,hd12,hd13,hd14,hd15,hd16,hd17,hd18,hd19

Error: cannot find which cluster host is the local host.
Hint: Is this node in the cluster? Did its IP address change?
Installation FAILED with errors.

Installation stopped before any changes were made.

I just made the Julia language work across all the nodes (which makes me think ssh and other configs are fine) so I don't know what is Vertica trying to find out.

 

[root@hd0 ~]# julia -p 1 --machinefile nodes --quiet
julia> nprocs()
40

Where nodes is simply a file that lists the same hosts that are listed in the install_vertica command (2 workers per node).

 

Could someone help me figure out the source of this problem?

 

Thanks in advance, cheers!

I had to also add the master node to the list of hosts.

pios

How to solve this problem?

 

 

Thakur

please pass the parameter " rpm " with full folder path and also include hd0 in the list of hosts

 

# /opt/vertica/sbin/install_vertica --hosts host_list --rpm package_name --dba-user dba_username
