Thanks Karan for input but found the issue of slowness in kubernetes while doing broadcast it takes 2 to 3 times than YARN . need to check why such a big difference. In our case we are doing around 40 tables manual broadcast as the size of tables is more than 10 mb. What can be done in kubernetes
Pls check if there are resource constraints on the pods/nodes especially if
they are shared.
MinIO connectivity performance needs to be checked.
With YARN and External Spark Shuffle, the sparkshuffle is a lot more
optimized, so we can experience slowness with spark on k8s, especially if
there is a
Hello Karan,I am using Spark open source in kubernetes and Spark mapr bundle in YARN.For launching job in both approach it takes same 10 secs .For shuffle I am using local in both yarn and kubernetes.Sent from my iPhoneOn Apr 11, 2025, at 11:24 AM, karan alang wrote:Hi Prem,Which distribution of
Hi Prem,
Which distribution of Spark are you using ?
how long does it take to launch the job ?
wrt Spark Shuffle, what is the approach you are using - storing shuffle
data in MinIO or using host path ?
regds,
Karan

Hello Team,
I have a peculiar case of Spark slowness.
I am using Minio as Object storage from where Spark reads & writes data. I
am using YARN as Master and executing a Spark job which takes ~5mins the
same job when run with Kubernetes as Master it takes ~8 mins .
I checked the Spark DAG in both a
