I am running HDP 2.3 and was capturing screenshots for a lesson under development for Slider. I created a Slider view, created the yarn home directory in HDFS, copied an HBase slider package to the appropriate location, and restarted Ambari server. It was then I realized the I had forgotten to install the Slider service on my cluster. Thinking it would be a great error message to capture, I went back to the Slider View, created the app per the wizard, and deployed - thinking it would error out and tell me that the service was not installed. To my surprise, the application ran without a problem, and the Slider View allowed me to perform the Flex and other actions with no issues. Because this is for a training class, I need to understand why this worked. Is there something special about the HBase slider package we make available that allows it to run on a cluster where the service is not installed, or does the HDP or Ambari support slider applications without the need to explicitly install the service? If that's true, what is it that installing Slider on HDP actually accomplishes? I will post screenshots in a comment below. Thanks in advance. ... View more

According to our docs, I should be able to download a Slider package for HBase at the following link: http://s3.amazonaws.com/dev.hortonworks.com/HDP/centos6/2.x/updates/2.3.2.0/slider-app-packages/hbase/slider-hbase-app-package-1.1.1.2.3.2.0-2950.zip However, I am getting a "forbidden" error when I attempt to access/download anything. Is there a reason for this? Is this available at an alternative location? ... View more

I have successfully uploaded a blueprint to an Ambari server. I am trying now to configure default repositories for HDP installation in our classroom lab environment, as per instructions here: https://cwiki.apache.org/confluence/display/AMBARI/Blueprints#Blueprints-Step4:SetupStackRepositories%28Optional%29 I have created the a file, named HDPRepo.test, per the instructions. The command I am using is based on what worked for the blueprint upload, but pointed at the repo URI per the instructions: curl -u admin:admin -i -H "X-Requested-By: jedentest1" -X POST -d @HDPRepo.test http://node1:8080/api/v1/stacks/HDP/versions/2.3/operating_systems/redhat6/repositories/HDP-2.3/ I can't find this demo'd anywhere on the web, so I'm flying a bit blind. The error being returned is: { "status" : 500, "message" : "Cannot create repositories."} My suspicion is that the documentation is missing some minor piece (possibly a cURL add-on, or perhaps the API URI isn't quite right) that makes this update of the base_url value work. Has anyone actually done this that can point out what I need to modify in my command? Thanks! ... View more
