This makes a lot of sense!

The answer to this question depends on the customers needs. In many cases, you would use an existing Microsoft AD implementation as the end-users are most likely using that to access the network anyway. You can implement a dedicated KDC, but it will add complexity.

@Gaurab D As Sunile mentions, there are a couple of steps to the process. You need to provide more detail about what steps you have completed. For the specific command you are using, Make sure you use: sudo -u yarn yarn rmadmin -addToClusterNodeLabels "x(exclusive=true),y(exclusive=false)"

Good catch! I'm glad you took the time to write up your findings for others to learn.

@Bharath Kumar K Adding the VBoxGuestAdditions.iso file to the VM doesn't actually install the guest additions. Once you add the ISO to the image, you have to install the guest additions. Here are the instructions for install the guest additions: https://wiki.centos.org/HowTos/Virtualization/VirtualBox/CentOSguest

@Gaurab D A single node label can have multiple nodes assigned to it. However, a single node can not belong to more than 1 node label. You are trying to label a single node with 2 different labels which is not supported. See: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.4.0/bk_yarn_resource_mgt/content/configuring_node_labels.html You can only assign one node label to each node. Also, if you do not specify a port, the node label change will be applied to all NodeManagers on the host.

For the Hive errors, it's looks like hive is having issues communicating with Zookeeper. If Zookeper won't startup, then that's not surprising. For the Ambari Agent errors, it looks like you have a corrupted json data file in your ambari-agent (/var/lib/ambari-agent/data/structured-out-status.json). Try moving the file to a different name like ".backup" and restart all of the services. I would do a "stop all" of the services, if it is available. Then try starting only Zookeeper to see if it comes up cleanly. After that, try starting the HDFS service. Then you can do a "start all".

Yes, that is what I was suggesting. For your ssh command, use a lowercase -p instead of uppercase -P.

The best bet is to connect to the sandbox with a terminal application that allows you to scroll like PuTTY on Windows or Terminal on Mac. You can also try running your command and redirecting the output to a file like:
mycommand > myoutput.txt
Then you can look at the file with: less myoutput.txt
