Re: Dynamic Scaling without Kubernetes

Wouldn't you need to run Spark on Hadoop in order to use YARN?  I believe that YARN only manages Hadoop nodes, not Spark workers directly.  Besides, what I read was that you would need some extra plug-ins to be able to get nodes managed dynamically. Our use case would be like this: 1. A

Re: Dynamic Scaling without Kubernetes

So Spark can dynamically scale on YARN, but standalone mode becomes a bit complicated — where do you envision Spark gets the extra resources from? On Wed, Oct 26, 2022 at 12:18 PM Artemis User wrote: > Has anyone tried to make a Spark cluster dynamically scalable, i.e., > adding a new worker

Dynamic Scaling without Kubernetes

Has anyone tried to make a Spark cluster dynamically scalable, i.e., adding a new worker node automatically to the cluster when no more executors are available upon a new job submitted?  We need to make the whole cluster on-prem and really lightweight, so standalone mode is preferred and no

Re: Running 30 Spark applications at the same time is slower than one on average

That just means G = GB mem, C = cores, but yeah the driver and executors are very small, possibly related. On Wed, Oct 26, 2022 at 12:34 PM Artemis User wrote: > Are these Cloudera specific acronyms? Not sure how Cloudera configures > Spark differently, but obviously the number of nodes is too

Re: Running 30 Spark applications at the same time is slower than one on average

Are these Cloudera specific acronyms?  Not sure how Cloudera configures Spark differently, but obviously the number of nodes is too small, considering each app only uses a small number of cores and RAM.  So you may consider increase the number of nodes.   When all these apps jam on a few

Hi All, I have a CDH5.16.2 hadoop cluster with 1+3 nodes(64C/128G, 1NN/RM + 3DN/NM), and yarn with 192C/240G. I used the following test scenario: 1.spark app resource with 2G driver memory/2C driver vcore/1 executor nums/2G executor memory/2C executor vcore. 2.one spark app will use 5G4C on

Yoohoo! Thanks Yuming for driving this release. A tiny step for Spark a huge one for my clients (who still are on 3.2.1 or even older :)) Pozdrawiam, Jacek Laskowski https://about.me/JacekLaskowski "The Internals Of" Online Books Follow me on
