Ambari Server and Web Client versions do not match

[#1]

Im using ambari 2.4.1 and HDP 2.5 which was running absolutely fine. I have tried installing apache eagle on the clsuter and in the process ran eagle-ambari.sh script and from then onwards, i cant open ambari with version mismatch error. There is no much info on the earlier posts.

Hi @Jay SenSharma yes the app verson was 2.0.0. i have upgraded ambari from 2.4.0 to 2.4.1. Not sure how 2.0.0 was in it and how it was working earlier.

I have reinstalled ambari-server but UI is still stuck and no file named set-ambari-version.sh is available in the cluster.

[root@server db]# find / -name set-ambari-version.sh

[root@server db]# date Fri May 26 15:24:23 IST 2017 [root@server db]#

You will not find that file in your file system. The "set-ambari-version.sh" script is only used when some one tries to build ambari from github and when making RPM it is used to set the version number.

As a user we simply download those RPMs from the ambari repo and install it. (Inside the RPM we do not ship that script)

Hi @Jay SenSharma I have removed the file app.js and reinstalled ambari server using yum. Now after reinstallation, app.js file is reflecting correct version. However after login, ambari UI is stuck in below screen.

We will need to see the Java Script call that is getting stuck.

We can do so by using the "Developer Tools".

For example open URL in Google Chrome and then click on the

"Google Chrome Menu" --> "More Tools" --> Debugger Tools

Can you please share the output of the Debugger tools Specially from the "Network" tab which tells the call that is keep trying to get the response.

.

Also try running the following Curl Command :

# curl -u admin:admin -i -H 'X-Requested-By: ambari' -X POST -d '{"wizard-data":"{\"userName\":\"admin\",\"controllerName\":\"\"}"}'http://ambari.example.com:8080/api/v1/persist

.

You will need to replace the credentials and the ambari server hostname in the above command.

Couldn't find much from the debugger tools. Curl has below details.

[root@server ambari-server]# curl -u admin:@dm1n -i -H 'X-Requested-By: ambari' -X POST -d '{"wizard-data":"{\"userName\":\"admin\",\"controllerName\":\"\"}"}' http://192.168.1.9:8080/api/v1/persist HTTP/1.1 202 Accepted X-Frame-Options: DENY X-XSS-Protection: 1; mode=block Set-Cookie: AMBARISESSIONID=sgdgux8qy76z18nlimhl2bo59;Path=/;HttpOnly Expires: Thu, 01 Jan 1970 00:00:00 GMT User: admin Content-Type: text/plain Content-Length: 0 Server: Jetty(8.1.19.v20160209)

While loading ambari UI ambari APIs also tries to read the whole cluster information's which also includes Alerts definition, That actually makes many DB calls.

Looks like your VM has some resource issues which is causing ambari to be very slow. (Thats why Ambari API calls are showing "ambari_server_performance" alert saying "Host resource exaustion")

https://github.com/apache/ambari/blob/release-2.5.0/ambari-server/src/main/resources/alerts.json#L43...

Can you try killing some of the processes manually like Oozie and Zeppelin and then restart ambari server to see if it loads fine.
