Normally, when you start the master, the slaves should also be started automatically. This, however, presupposes that you've configured the slaves. In the $SPARK_HOME/conf directory there should be a slaves or slaves.template file. If it only contains localhost, then you have not set up any worker nodes.
Also note that SSH from the master to the slaves must be enabled for the user that runs the Thrift server. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/JDBC-Cluster-tp27012p27046.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
