Getting back on the horse (or elephant?) this week with a three part question for Week 7, all about the Hadoop HDFS IP configurations.
Challenge 7 (Nov 16-23) Part 1 Domains and Such (15)
What is the IP address of the HDFS primary node?
Challenge 7 (Nov 16-23) Part 2 (5)
Is the IP address on HDFS-Primary dynamically or statically assigned?
Since the IP was set here in the hosts file prior I assumed it was statically assigned but wanted to verify before entering that as the answer just in case it was a one and done answer question. Digging a little bit into the file system a little bit, we can look at the following file which contains more network configurations:
We can see the primary network interface information with the syntax as:
iface ens33 inet static
Here shows the iface command followed by the following:
interface = ens33
address_family = inet
method = static
So we can see in method it's set to "Static", hence the answer should be "statically".
Challenge 7 (Nov 16-23) Part 3 (5)
What is the interface name name for the primary HDFS node?
We got this answer from the past question file in "interfaces". We see that the node network interface was "ens33".
I was a bit relieved that this week's questions were a bit easier than the last. Onward and upward to Week 8!
