Job history server ui not getting connected

AnuKarthi — Fri, 16 Sep 2022 10:15:25 GMT

Dear Hortonworks, Am using hdp2.4 sandbox, once my job finished (eg. sqoop import job) not able to view the history logs through resource manager UI. If i click history am getting error as below. All the quick links in MR2 getting the same even if history server is started and running fine.

http://sandbox.hortonworks.com:19888/ –> Job history server UI

This site can’t be reached

sandbox.hortonworks.com’s server DNS address could not be found.

Looking yours support!

Please use : http://127.0.0.1:19888

If you are using linux then add below entry in /etc/hosts file

127.0.0.1    sandbox.hortonworks.com

If you are using windows then add above entry in C:\Windows\System32\drivers\etc\hosts

@VENKATESH M

Please find out the actual IP assigned to the sandbox by running following. Using this IP you should be able to access all the UIs.

ifconfig eth0 | grep "inet addr"

I sort out the issue manish, thanks for your support, if i update entry of same ip in C:\Windows\System32\drivers\etc\hosts, am able to view the history logs through Application master itself

Please keep changing the IP in any URL which does not have the desired IP address. Then it should work.

OR you can do following to get rid off this error as mentioned by: @Kuldeep Kulkarni:

Add below line in /etc/hosts file (in Mac/Linux). in Windows it is C:\Windows\System32\drivers\etc\hosts:

192.168.183.132 sandbox.hortonworks.com
