Hi There,
I'm starting using spark and got a rookie problem. I used the standalone and
master only, and here is what I did:
./sbin/start-master.sh
./bin/pyspark
When I tried the example of wordcount.py, which my input file is a bit big,
about I got the out of memory error, which I excerpted and pasted in below.
I have 60G RAM, in my log file, I found this:
Spark Command: java -cp
::/home/ubuntu/spark/conf:/home/ubuntu/spark/assembly/target/scala-2.10/spark-assembly-1.1.0-SNAPSHOT-hadoop1.0.4.jar
-XX:MaxPermSize=128m -Dspark.akka.logLifecycleEvents=true -Xms512m -Xmx512m
org.apache.spark.deploy.master.Master --ip ip-10-123-146-183 --port 7077
--webui-port 8080
Any help please?
