Spark on YARN, HowTo kill executor or individual task?
Hi there!
I have weird issue that appears only when tasks fail at specific stage. I
would like to imitate failure on my own.
The plan is to run problematic app and then kill entire executor or some
tasks when execution reaches certain stage.
Is it do-able?

Yeah, then the easiest would be to fork spark and run using the forked
version, and in case of YARN it should be pretty easy to do.
git clone https://github.com/apache/spark.git
cd spark
export MAVEN_OPTS="-Xmx4g -XX:ReservedCodeCacheSize=512m"
./build/mvn -DskipTests clean package
./dev/make-distribution.sh --name custom-spark --tgz -Phadoop-2.7 -Phive
-Pyarn
ls -la spark-2.4.0-SNAPSHOT-bin-custom-spark.tgz
scp spark-2.4.0-SNAPSHOT-bin-custom-spark.tgz cluster:/tmp
export SPARK_HOME="/tmp/spark-2.3.0-SNAPSHOT-bin-custom-spark"
cd $SPARK_HOME
mv conf conf.new
ln -s /etc/spark/conf conf
echo $SPARK_HOME
spark-submit --version

I tried a similar approach, it works well for user functions. but I need to
crash tasks or executor when spark application runs "repartition". I didn't
any away to inject "poison pill" into repartition call :(

something like this
import org.apache.spark.TaskContext
ds.map(r => {
val taskContext = TaskContext.get()
if (taskContext.partitionId == 1000) {
throw new RuntimeException
}
r
})

I need to crash task which does repartition.

What blocks you to put if conditions inside the mentioned map function?

Yeah, but I don't need to crash entire app, I want to fail several tasks or
executors and then wait for completion.

Another approach is adding artificial exception into the application's
source code like this:
val query = input.toDS.map(_ / 0).writeStream.format("console").start()

Hi BR,
thanks for your reply. I want to mimic the issue and kill tasks at a
certain stage. Killing executor is also an option for me.
I'm curious how do core spark contributors test spark fault tolerance?

Hi Serega,
If I understand your problem correctly you would like to kill one executor
only and the rest of the app has to be untouched.
If that's true yarn -kill is not what you want because it stops the whole
application.
I've done similar thing when tested/testing Spark's HA features.
- jps -vlm | grep
"org.apache.spark.executor.CoarseGrainedExecutorBackend.*applicationid"
- kill -9 pidofoneexecutor
Be aware if it's a multi-node cluster check whether at least one process
runs on a specific node(it's not required).
Happy killing...
BR,
