java.lang.UnsatisfiedLinkError: no mesos in java.library.path

Question

我正在尝试为 Mesos 集群部署模式配置 spark job-server。我在 jobserver 配置中设置了 spark.master = "mesos://mesos-master:5050"。

当我尝试在作业服务器上创建上下文时，失败并出现以下异常：

[2017-04-19 14:09:42,346] ERROR .jobserver.JobManagerActor [] [akka://JobServer/user/jobManager-42-881e-b37be6e443dd] - Failed to create context test-context, shutting down actor

我已将环境变量 MESOS_NATIVE_JAVA_LIBRARY 设置为指向 libmesos.so 的正确位置此外，我能够使用命令行中的 spark submit 成功提交作业：

 ./bin/spark-submit --class org.apache.spark.examples.SparkPi --master mesos://mesos-master:5050 /pathto/spark/examples.jar 100

这意味着我的 mesos 集群设置正在运行。

我是否遗漏了任何需要专门为 spark-jobserver 完成的配置？

Answer 1

我正在为用户设置 MESOS_NATIVE_JAVA_LIBRARY env 变量，我是运行具有 Sudo 权限的作业服务器。

Answer 2

将MESOS_NATIVE_JAVA_LIBRARY设置为libmesos.so

的路径

示例：

    $ export MESOS_NATIVE_JAVA_LIBRARY=/usr/local/lib/libmesos.so
