如何使用 Supervisord 自动启动 Apache Spark 集群？

Question

启动 Apache Spark 集群通常是通过代码库提供的 spark-submit shell 脚本完成的。但是，问题是每次集群关闭并重新启动时，都需要执行那些shell脚本来启动spark集群。

Supervisord 非常适合管理进程，似乎是重启后自动启动 spark 进程的理想选择。

但是，通过

启动主进程后

command=/usr/lib/jvm/java-1.7.0-openjdk.x86_64/bin/java -cp :/path/spark-1.3.0-bin-cdh4/sbin/../conf:/path/spark-1.3.0-bin-cdh4/lib/spark-assembly-1.3.0-hadoop2.0.0-mr1-cdh4.2.0.jar:/path/spark-1.3.0-bin-cdh4/lib/datanucleus-api-jdo-3.2.6.jar:/path/spark-1.3.0-bin-cdh4/lib/datanucleus-core-3.2.10.jar:/path/spark-1.3.0-bin-cdh4/lib/datanucleus-rdbms-3.2.9.jar:etc/hadoop/conf -XX:MaxPermSize=128m -Dspark.akka.logLifecycleEvents=true -Xms512m -Xmx512m org.apache.spark.deploy.master.Master --ip master.mydomain.com --port 7077 --webui-port 18080

和工作进程

command=/usr/lib/jvm/java-1.7.0-openjdk.x86_64/bin/java -cp :/path/spark-1.3.0-bin-cdh4/sbin/../conf:/path/spark-1.3.0-bin-cdh4/lib/spark-assembly-1.3.0-hadoop2.0.0-mr1-cdh4.2.0.jar:/path/spark-1.3.0-bin-cdh4/lib/datanucleus-api-jdo-3.2.6.jar:/path/spark-1.3.0-bin-cdh4/lib/datanucleus-core-3.2.10.jar:/path/spark-1.3.0-bin-cdh4/lib/datanucleus-rdbms-3.2.9.jar:etc/hadoop/conf -XX:MaxPermSize=128m -Dspark.akka.logLifecycleEvents=true -Xms512m -Xmx512m org.apache.spark.deploy.worker.Worker spark://master.mydomain.com:7077

我在提交我的 spark 申请后遇到了以下错误：

有谁知道如何通过supervisord管理spark进程？

我也愿意接受其他解决方案。

火花大师可以运行在前台

command=/path/spark-1.3.0-bin-cdh4/sbin/../bin/spark-class org.apache.spark.deploy.master.Master --ip master.mydomain.com --port 7077 --webui-port 18080

还有工人

command=/path/spark-1.3.0-bin-cdh4/sbin/../bin/spark-class org.apache.spark.deploy.worker.Worker spark://master.mydomain.com:7077
