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，都需要执行这些shell脚本来启动spark集群。

Supervisord非常适合管理流程，并且似乎是重启后自动启动spark流程的理想选择。

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

的工作流程

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

提交spark应用程序后，我最终得到以下错误：

有谁知道如何通过supervisord管理火花过程？

我也对替代解决方案持开放态度。

可以通过

在前台运行spark master

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

和工人

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

如何使用Supervisord自动启动Apache Spark集群？
