Github user AhyoungRyu commented on the issue: https://github.com/apache/zeppelin/pull/1369 @doanduyhai Sorry for my late response and thanks for the kind reminder. I tested again and checked the below issues I mentioned are gone :D >(edit interpreter -> add `one:two:1.1.1` to the dependency table -> save ) Two things are different with master branch. 1. Only Spark interpreter throw the ng-toast error message. 2. The other interpreters' status circle is looping infinitely. It need to be reload to turn to red and also don't show the ng-toast error message. But I found another issues in the latest update. 1. edit Alluxio interpreter -> add `aaa:bbb:1.1.1` to the dependency field -> go to another page like "Credential" or "Configuration" -> The `ng-toast` error message is still shown as @astroshim said in the above comment. How about adding some timeout property to the message? 2. edit Alluxio -> add `aaa:111:1.1.1` & `bbb:111.2.2.2` to the dependency field -> save I think the number of errors and reasons need to be same. Currently, while the number of errors keeps increasing whenever I save the change, the only one reason "Could not find artifact aaa:111:jar:1.1.1 in central (http://repo1.maven.org/maven2/)" is shown. Need to show "Could not find artifact bbb:111.2.2.2 in central (http://repo1.maven.org/maven2/)" as well if we want to show the number of errors. <img width="1263" alt="screen shot 2016-09-18 at 9 37 55 pm" src="https://cloud.githubusercontent.com/assets/10060731/18615730/026b5b42-7de9-11e6-9294-c8a88687f896.png"> The number of error should be 2 in the above case I guess. But as you can see the number is 1 since `checkDownloadingDependencies()` is called only one time.
