Hi Expert,
Hadoop version: 2.4
Spark version: 1.3.1
I am running the SparkPi example application.
bin/spark-submit --class org.apache.spark.examples.SparkPi --master
yarn-client --executor-memory 2G lib/spark-examples-1.3.1-hadoop2.4.0.jar
20000
The same command sometimes gets WARN ReliableDeliverySupervisor, sometimes
does not.
Some runs are successful even with the WARN
bin/spark-submit --class org.apache.spark.examples.SparkPi --master
yarn-client --executor-memory 2G lib/spark-examples-1.3.1-hadoop2.4.0.jar
10000

library for your platform... using builtin-java classes where applicable
Pi is roughly 3.141633956

Pi is roughly 3.141625776
Also, the spark ui only available when I set --master to local.
What could have caused those issues ?
Thanks,
Xiaohe
