Failed at "Install, Start and Test"

[#1]

At the very beginning of installing Apache Accumulo I encountered the following error:

W: Failed to fetch http://my_pc_hostname/HDP-UTILS-1.1.0.21/repos/ubuntu14/dists/HDP-UTILS/main/binary-i386/Packages 503 Service Unavailable

Because I'm in a environment where no internet access is available I followed the steps described in the official document(https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/), made local repositories on a Apache2

server. My specs are

OS:ubuntu 14

Ambari:2.4.0.1

HDP:2.5

From the error message above, I guess the ambari-agent tries to reach the "http://my_pc_hostname/" domain which is my local Apache2 server hostname but mistakenly looking for it at WAN.

Stuck on this error for a few days.

Any help is greatly appreciated!!

Is this happening because during building the cluster I specified just each node's hostname rather than the FQDN?

@Yu Song

"503 Service Unavailable" error usually indicates the server side error. In this case it looks like you are using your own custom local repository. http://my_pc_hostname/HDP-UTILS-1.1.0.21/repos

So you will need to check the WebServer log (Like: Apache2 httpd logs) to see why is it showing 503 error.

Also are you able to open that URL in browser? I guess you will get same 503 error. means issue with your apache2 config.

http://my_pc_hostname/HDP-UTILS-1.1.0.21/repos/ubuntu14/dists/HDP-UTILS/main/binary-i386/Packages

Actually, I have no problem accessing the url from browser :

http://my_pc_hostname/HDP-UTILS-1.1.0.21/repos/ubuntu14/dists/HDP-UTILS/main/binary-i386/Packages

wget http://my_pc_hostname/HDP-UTILS-1.1.0.21/repos/ubuntu14/dists/HDP-UTILS/main/binary-i386/Packages

returns the same 503 error but adding --no-proxy option to wget resolves the issue.

As such, I think this is an issue of not specifying FQDN?
