Custom ambari view not showing in the view menu after deploying

anis016 — Thu, 17 Aug 2017 17:33:16 GMT

Hello,

I am trying to deploy my custom view in the Ambari. However, I cannot see my custom view after deploying. I am following the procedure given here: Ambari-View Example, mainly following the basic view: HelloWorld.

After downloading the code, I followed the below procedure

Obtain the View package. For example, helloworld-view-1.0-SNAPSHOT.jar.
On the Ambari Server host, browse to the views directory.
cd /var/lib/ambari-server/resources/views
Copy the helloworld-view-1.0-SNAPSHOT.jar into this folder.
Restart Ambari Server.
ambari-server restart
Check in the Ambari web UI -> View menu,
Nothing is displayed. Log is also showing nothing suspicious.

Log:

Re: Custom ambari view not showing in the view menu after deploying

Login to Ambari UI --> "Admin" (Drop down top right corner) --> Manage Ambari --> Views --> "Hello world View" (something like this)

Click on the "Create Instance" button there and fill the details. And then it should be listed in the drop down menu of Views.

Also is there any specific reason that you are specifying 1.7.0 version for ambari there?

I used the following to test locally.

    <dependency>
      <groupId>org.apache.ambari</groupId>
      <artifactId>ambari-views</artifactId>
      <version>2.5.0.0</version>
    </dependency>

@Jay SenSharma

Thank you for your quick reply. However, I cant see the menus that you have told. Please check the screenshots of the menus.

screen1:

screen2:

Moreover, I used this below repo earlier, but I was getting this issue. It seems it is not available. so, I tried with 2.0.0.0 version and then 1.7.0.0 version.

<dependency>
 <groupId>org.apache.ambari</groupId>
 <artifactId>ambari-views</artifactId>
 <version>2.5.0.0</version>

@Sayed Anisul Hoque

Looks like you logged in to ambari as "raj_ops" user. This user does not have permission to view the "Hello World View".

So login to ambari as "admin" with password "admin" user and then Navigate to :

Ambari UI --> "Admin" (Drop down top right corner) --> Manage Ambari --> Views --> "Hello world View" (Click here)

Now give the permission to the "raj_ops" user to see the view as following:

Fantastic !

It is now working.. Login into Admin account did the trick.

Thank you a bunch 🙂 @Jay SenSharma

If you have a time, can you please tell about the maven dependency. I am wondering, how you are able to use this dependency because I searched through the maven repo and the updated one is 2.0.0.0

<dependency>
	<groupId>org.apache.ambari</groupId>
	<artifactId>ambari-views</artifactId>
	<version>2.5.0.0</version>
</dependency>

However, I really appreciate your help. I was struggling with this for past 2 days ! phew ...
