Hi all,
I run start-master.sh to start standalone Spark with
spark://192.168.1.164:7077. Then, I use this command as below, and it's OK:
./bin/spark-shell --master spark://192.168.1.164:7077
The console print correct message, and Spark context had been initialised
correctly.
However, when I run app in IntelliJ Idea using spark conf like this:
val sparkConf = new SparkConf().setAppName("FromMySql")
.setMaster("spark://192.168.1.164:7077")
.set("spark.akka.heartbeat.interval", "100")
val sc = new SparkContext(sparkConf)
val sqlContext = new SQLContext(sc)
It can't talk to spark and print these error messages:
ReliableDeliverySupervisor: Association with remote system
[akka.tcp://sparkMaster@192.168.1.164:7077] has failed, address is now gated
for [5000] ms. Reason is: [Disassociated].
If I changed the conf to local[*], it's ok. After I packaged my app then use
spark-submit command, the communication between local and remote actor is
OK. It's very strange!
Then I debugged it, and the remote actor can be fetched correctly in the
tryRegisterAllMasters() method of AppClient:
def tryRegisterAllMasters() {
for (masterAkkaUrl <- masterAkkaUrls) {
logInfo("Connecting to master " + masterAkkaUrl + "...")
val actor = context.actorSelection(masterAkkaUrl)
actor ! RegisterApplication(appDescription)
}
}
After actor send the RegisterApplication message, it seems like the message
is not routed to the remote actor, so registering operation is not finished,
then failed.
I don't know what is the reason. Who know the answer?
Regards,
Yi
