Hi,
I can't seem to understand why all created executors always fail.
I have a Spark standalone cluster setup make up of 2 workers and 1 master.
My spark-env looks like this:
SPARK_MASTER_IP=192.168.2.11
SPARK_LOCAL_IP=192.168.2.11
SPARK_MASTER_OPTS="-Dspark.deploy.defaultCores=4"
SPARK_WORKER_CORES=4
SPARK_WORKER_MEMORY=6g
>From the Spark logs, I get this:

I appreciate any kind of help.
