So I had some internal discussion and the real answer is dynamic scaling down is hard to achieve. You can scale down using cloudbreak, but cloudbreak does a decommissioning of the service before it kills the docker image. So you can technically do it, but as you do, HDFS will try to relocate the replicas which is going to be time consuming. The alternate is to use something like WASB, where the data is not in HDFS local store but in WASB. The storage and compute are separate so you can turn down instances easily. ... View more

Hi guys, thanks so much for what a great tutorial @Shivaji Dutta I have been trying to recreate your tutorial but with Centos7 so, guys I have a problem creating the docker image with Centos7 actually because your script fails in the steps to start the services as ssh and the other stuff. I share with you the file to create the docker image and I hope you can give me a hand to run it. @Vincent Jiang @Hajime dockerfile.txt Thanks so much ... View more

Throwing my 2 cents in since I've spent an insane amount of time working with Solr on this exact problem. ConcurrentUpdateSolrClient is really easy to get going and you can get a high throughput just by increasing the number of threads. However, at some point it just won't be scalable or efficient once you have a bunch of Solr nodes. If you are using Solr Cloud, then the CloudSolrClient is definitely the recommended way to go but, in my experience, it is much, much harder to get high throughput. Batching documents is pretty much a requirement. You can't really just increase the number of threads because each one opens a connection to Zookeeper. If you decide to go with CloudSolrClient, take a look at the code in storm-solr. ... View more
