-------------------------------------
Summary: scheduler with blacklisting doesn't appear to pick up new
executor added
Key: SPARK-33031
URL: https://issues.apache.org/jira/browse/SPARK-33031
Project: Spark
Issue Type: Bug
Components: Scheduler
Affects Versions: 3.0.0
Reporter: Thomas Graves
I was running a test with blacklisting on yarn (and standalone mode) and all
the executors were initially blacklisted. Then one of the executors died and
we got allocated another one. The scheduler did not appear to pick up the new
one and try to schedule on it though.
You can reproduce this by starting a master and slave on a single node, then
launch a shell like where you will get multiple executors (in this case I got 3)
$SPARK_HOME/bin/spark-shell --master spark://yourhost:7077 --executor-cores 4
--conf spark.blacklist.enabled=true
>From shell run:
{code:java}
import org.apache.spark.TaskContext
val rdd = sc.makeRDD(1 to 1000, 5).mapPartitions { it =>
val context = TaskContext.get()
if (context.attemptNumber() < 2) {
throw new Exception("test attempt num")
}
it
}{code}
Note that I tried both with and without dynamic allocation enabled.
