Vlad Komarov created SPARK-2645:
-----------------------------------
Summary: Spark driver calls System.exit(50) after calling
SparkContext.stop() the second time
Key: SPARK-2645
URL: https://issues.apache.org/jira/browse/SPARK-2645
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.0.0
Reporter: Vlad Komarov
In some cases my application calls SparkContext.stop() after it has already
stopped and this leads to stopping JVM that runs spark driver.
E.g
This program should run forever
{code}
JavaSparkContext context = new JavaSparkContext("spark://12.34.21.44:7077",
"DummyApp");
try {
JavaRDD<Integer> rdd = context.parallelize(Arrays.asList(1, 2, 3));
rdd.count();
} catch (Throwable e) {
e.printStackTrace();
}
try {
context.cancelAllJobs();
context.stop();
//call stop second time
context.stop();
} catch (Throwable e) {
e.printStackTrace();
}
Thread.currentThread().join();
{code}
but it finishes with exit code 50 after calling SparkContext.stop() the second
time.
Also it throws an exception like this
{code}
