I have two questions to ask:
# I wrote a demo referring to the official website, but it didn't meet my
expectations. I don't know if there was a problem with my writing.I hope that
when I use the following fairscheduler.xml, pool1 always performs tasks before
pool2
# What is the relationship between "spark.scheduler.mode" and
"{{{}schedulingMode{}}}" in fairscheduler.xml？
{code:java}
object MultiJobTest {
def main(args: Array[String]): Unit = {
val conf = new SparkConf()
conf.setAppName("test-pool").setMaster("local[1]")
conf.set("spark.scheduler.mode", "FAIR")
conf.set("spark.scheduler.allocation.file",
"file:///D:/tmp/input/fairscheduler.xml")
val sparkContext = new SparkContext(conf)
val data: RDD[String] = sparkContext.textFile("file:///D:/tmp/input/input.txt")
val rdd = data.flatMap(_.split(","))
.map(x => (x(0), x(0)))
new Thread(() => {
sparkContext.setLocalProperty("spark.scheduler.pool", "pool1")
rdd.foreachAsync(x => {
println("1======start==" + new SimpleDateFormat("HH:mm:ss").format(new Date()))
Thread.sleep(10000)
println("1======end==" + new SimpleDateFormat("HH:mm:ss").format(new Date()))
})
}).start()
new Thread(() => {
sparkContext.setLocalProperty("spark.scheduler.pool", "pool2")
rdd.foreachAsync(x => {
println("2======start==" + new SimpleDateFormat("HH:mm:ss").format(new Date()))
Thread.sleep(10000)
println("2======end==" + new SimpleDateFormat("HH:mm:ss").format(new Date()))
})
}).start()
TimeUnit.MINUTES.sleep(2)
sparkContext.stop()
}
