Here is a link for builds of 1.4 RC2:
http://people.apache.org/~pwendell/spark-releases/spark-1.4.0-rc2-bin/
<http://people.apache.org/%7Epwendell/spark-releases/spark-1.4.0-rc2-bin/>
For a mvn repo, I believe the RC2 artifacts are here:
https://repository.apache.org/content/repositories/orgapachespark-1104/
A few experiments you might try:
1. Does spark-shell work? It might start fine, but make sure you can
create an RDD and use it, e.g., something like:
val rdd = sc.parallelize(Seq(1,2,3,4,5,6))
rdd foreach println
2. Try coarse grained mode, which has different logic for executor
management.
You can set it in $SPARK_HOME/conf/spark-defaults.conf file:
spark.mesos.coarse true
Or, from this page
<http://spark.apache.org/docs/latest/running-on-mesos.html>, set the
property in a SparkConf object used to construct the SparkContext:
conf.set("spark.mesos.coarse", "true")

Hello,
I assume I am running spark in a fine-grained mode since I haven't
changed the default here.
One question regarding 1.4.0-RC1 - is there a mvn snapshot
repository I could use for my project config? (I know that I have
to download source and make-distribution for executor as well)
thanks

Hello,
I am using Spark 1.3.1-hadoop2.4 with Mesos 0.22.1 with
zookeeper and running on a cluster with 3 nodes on 64bit ubuntu.
My application is compiled with spark 1.3.1 (apparently with
mesos 0.21.0 dependency), hadoop 2.5.1-mapr-1503 and akka
2.3.10. Only with this combination I have succeeded to run
spark-jobs on mesos at all. Different versions are causing
class loader issues.
I am submitting spark jobs with spark-submit with
mesos://zk://.../mesos.
Are you using coarse grained or fine grained mode?

It looks like an inconsistent state on the Mesos scheduler. It
tries to launch a task on a given slave before the executor has
registered. This code was improved/refactored in 1.4, could you
try 1.4.0-RC1?
Yes and note the second message after the error you highlighted;
that's when the executor would be registered with Mesos and the local
object created.
