Hi Philip, The cluster metrics in the screenshot attached shows that there are no active nodes. Have you started any Node Manager process ?

The code snippet which you have mentioned is correct. But it also has a check that if the number of active application is less than 1, this check wont be performed. And it seems you have only one application. - Sunil On Wed, Jun 15, 2016 at 12:27 PM Varun saxena <[email protected]<mailto:[email protected]>> wrote: Can you open the Resource Manager(RM) UI and share screenshot of main RM page.

I don’t think anything on the cluster is being used – see below I’m not sure how to get my “total cluster resource size” – please advise how to get this?

You have mentioned that there is only default queue here, so that wont be a problem. Few questions: - How much is your total cluster resource size and how much of cluster resource is used now ? - Is there any other application were running in cluster and whether it was taking full cluster resource.? This is a possibility since you now gave whole queue's capacity for AM containers. - Do you have multiple users in your cluster who runs applications other that this hive job? If so, yarn.scheduler.capacity.<queue-path>.minimum-user-limit-percent will have impact on AM resource usage limit. I think you can double check this. - Sunil On Wed, Jun 15, 2016 at 8:47 AM Phillip Wu <[email protected]<mailto:[email protected]>> wrote: Hi, I'm new to Hadoop and Hive.

Limits on each queue are directly proportional to their queue capacities and user limits. Specified as a float - ie 0.5 = 50%. Default is 10%. This can be set for all queues with yarn.scheduler.capacity.maximum-am-resource-percent and can also be overridden on a per queue basis by setting yarn.scheduler.capacity.<queue-path>.maximum-am-resource-percent" Can someone tell me how to fix this?
