Subject Getting started : Spark on YARN issue
Date Thu, 19 Jun 2014 13:04:03 GMT
I am trying to run Spark on YARN. I have a hadoop 2.2 cluster (YARN  +
HDFS) in EC2. Then, I compiled Spark using Maven with 2.2 hadoop profiles.
Now am trying to run the example Spark job . (In Yarn-cluster mode).

>From my *local machine. *I have setup HADOOP_CONF_DIR environment variable
correctly.

➜  spark git:(master) ✗ /bin/bash -c "./bin/spark-submit --class
org.apache.spark.examples.SparkPi --master yarn-cluster --num-executors 2
--driver-memory 2g --executor-memory 2g --executor-cores 1

Its able to talk to Resource Manager
Then it puts the example.jar file to HDFS and it fails. Its trying to write
to datanode. I verified that 50010 port is accessible through local
machine. Any idea whats the issue here ?
One thing thats suspicious is */10.180.150.66:50010
<http://10.180.150.66:50010> - it looks like its trying to connect using
private IP. If so, how can I resolve this to use public IP.*

Thanks
Praveen
