Home built Hadoop analytics cluster: Part 4

Home built Hadoop analytics cluster: Part 4

So yay!  As mentioned for my next goals in my previous post, I finally got the remaining two boxes built out and added into my home network.  I opted to put the Hadoop cluster on it's own subnet with a dedicated unmanaged switch only for the cluster (primary and nodes).

I added the agent and metrics to all of the nodes and rebooted the servers.

Then I followed the instructions to set up the cluster, naming it "ds730" after the class that I'm currently taking - DS730: Big Data - High Performance Computing.

I also made sure I had DNS setup correctly by modifying /etc/systemd/resolved.conf and fixed my name resolution issues.

Removed firewall rules.

Removed timedatectl by doing: sudo timedatectl set-ntp no

Then installed ntp: sudo apt install ntp

Now I need to look at installing some database drivers, however I think I'm going to call it a night.
