Subject Re: graphframes on cluster
Date Fri, 22 Sep 2017 10:23:24 GMT
sorry for posting without complete information

I am connecting to spark cluster with the driver program as the backend of
web application. This is intended to listen to job progress and some other
work. Below is how I am connecting to the cluster

sparkConf = new SparkConf().setAppName("isolated test")
   .setMaster("spark://master:7077")
    .set("spark.executor.memory","6g")
    .set("spark.driver.memory","6g")
    .set("spark.driver.maxResultSize","2g")
    .set("spark.executor.extrajavaoptions","-Xmx8g")

.set("spark.jars.packages","graphframes:graphframes:0.5.0-spark2.1-s_2.11")
    .set("spark.jars","/home/usr/jobs.jar"); //this is shared location
Linux machines and has the required java classes

the crash occurs at

gFrame.connectedComponents().setBroadcastThreshold(2).run();

with exception

Exception in thread "main" org.apache.spark.SparkException: Job aborted due

after googling around..this appears to be related to dependencies but I
don't have much dependencies apart from a few POJOs which have been
included through context

regards,
Imran
