Hi, I am using spark-0,8,1, and what's the meaning of spark.driver.host? I ran SparkPi failed.(either yarn-standalone or yarn-client)
It was 'Hostname or IP address for the driver to listen on.' in the document. but what host the Driver will listen on? the RM on the yarn? if yes, I configured spark.driver.host in the spark-env.sh as resource manager host and port: export SPARK_DAEMON_JAVA_OPTS="-Dspark.driver.host=10.2.8.1 -Dspark.driver.port=8032" but it doesn't work. I find in the log: WARN yarn.ApplicationMaster: Failed to connect to driver at null:null, retrying ... Even if I added these two system env variables to the JAVA_OPTS in the bin/spark-class, it also doen't work, please help. Any inputs are appreciated.
