I get the following screen while installing because of the error
The installation has not completed because of the zookeeper failing to pass the smoke test thus halting the processes further and giving 100% complete and with warning error on the installation page I have attached the zookeeper.txt file which shows the error.

Failed connect to node3.dtitsupport247.net:50075; No route to host !! Your hostnode3 is not reachable .. most probable issue wit the network setting routing tables. - Verify the entries in your /etc/hosts - Check the default gateway - check the firewall is off Just check that you didn't miss a step in the attached doc Then retry !!

I have experienced this several times.
Hit next
Move forward
Then you can run zk service check later once you are on dashboard
It's new install...no Kerberos in the pic

@Neeraj Sabharwal This is a fresh installation of a cluster, there is no kerberos been configured here in this cluster.
Even I refreshed this page but the same this happens, I dont want to reconfigure and reinstall? can we do something here

I know there is no kerberos. Don't refresh the page
Hit next and accept...you will come out install wizard then you can run zk check

I did next and completed the installations but many services are not running including. do you have a link which I can refer to? I am not sure what has caused the installation failure so very difficult to decide what step has to be done. I am installing it for the first time

That's expected. Now, start HDFS, MapReduce, Yarn, Zookeeper, Hive and other services manually
FYI: Your install did not fail. It's service check only and I have experienced it many times.
Install finishes at 33% then service start etc. starts.

Yes, I have been able to successfully turn up the services of HDFS but for MapReduce the history server gives an error. Nt sure why am i getting this error:

@Kunal Gaikwad See this
Failed connect to node3.dtitsupport247.net:50075; No route to host
Make sure datanodes are up and connection between servers is working.

Yes, the datanode and the namenode is up, but I noticed that from the hdfs service page from the quick link I am unable to see anything on the NameNode UI link, it says webpage not available, guess that is the reason why it is not able to establish a connection if I am not wrong? what can I do here?
my core-site.xml has
<value>hdfs://node1.dtitsupport247.net:8020</value>
even changing the port no. here from 8020 to 50070 does not help, none of the quicklinks are opening, says page does not exists
I tried running:
ps -ef | grep hadoop | grep -P 'namenode|datanode|tasktracker|jobtracker'
I have attached the output for it: outpt1.txt

@Kunal Gaikwad Is node1.dtitsupport247.net FQDN? Are you able to reach that url at all from you laptop?
