I faced a similar issue and had to do two things;
1. Submit Kryo jar with the spark-submit
2. Set spark.executor.userClassPathFirst true in Spark conf

You can use Spark MLlib

As of now, we are basically serializing the ML model and then deserialize
it for prediction at real time.

Any thoughts?

Hi All,
I'd like to apply a chain of Spark transformations (map/filter) on a given
JavaRDD. I'll have the set of Spark transformations as Function, and
even though I can determine the classes of T and A at the runtime, due to
the type erasure, I cannot call JavaRDD's transformations as they expect
If you press on the +details you could see the code that takes time. Did
you already check it?

Can it be the limited memory causing this slowness?

Hi,
For a fairly large dataset, 30MB, KMeansModel.computeCost takes lot of time
(16+ mints).
It takes lot of time at this task;
org.apache.spark.rdd.DoubleRDDFunctions.sum(DoubleRDDFunctions.scala:33)
org.apache.spark.mllib.clustering.KMeansModel.computeCost(KMeansModel.scala:70)
Can this be im
Hi All,
I'm facing a quite strange case, where after migrating to Spark 140, I'm
seen SparkMLLib produces different results when runs on local mode and
cluster mode. Is there any possibility of that happening? (I feel this is
an issue in my environment, but just wanted to get confirmed.)
Thanks.
Thanks Akhil!

Thanks Zhan! Was this introduced from Spark 1.2? or is this available in
Spark 1.1 ?

Hi All,
Is there a way to disable the Spark UI? What I really need is to stop the
startup of the Jetty server.
