Yarn Config Screen in Ambari not refreshing

wgonzalez — Thu, 28 Apr 2016 06:22:53 GMT

I have an issue where the screen for YARN Configs tab in ambari is not refreshing. (Get eternal spinning wheel but never refreshes).

All other Config tabs work.

All other tabs for YARN (Summary, Heatmaps) work.

Upon closer inspection with the Developer Tools in chrome, I see an "Uncaught Error: Invalid Path" in the JS Console (see screenshot).

Ideas? hcc.png

@William Gonzalez Please inform about following:

1) The ambari release version on which you are hitting this issue.

2) What is the Database URL config value on Hive service config page?

3) The attached image of JS error has a trace. Please click on first occurrence of app.js line in that trace. That will navigate to the JS source code that is throwing this error. Please attach image of that.

@William Gonzalez

Not sure which version of ambari are you using but the similar issue was reported in : https://issues.apache.org/jira/browse/AMBARI-12133 Which was later fixed in Ambari web 2.1.1 version.

Thanks Guys.

Both answers helped.

I had the wrong DNS name in Database URL config value on Hive service.

Hive is NOT being used in this cluster, so I did not think to check that value.

Thanks to both.
