容器在 mapreduce 任务期间以非零退出代码 1 错误退出

Container exited with a non-zero exit code 1 error during mapreduce task

在 hadoop 中执行 jar 时,出现以下错误:

16/11/04 18:32:59 INFO mapreduce.Job: Task Id : attempt_1478261728730_0005_m_000000_2, Status : FAILED

这是应用程序日志:

Native code library failed to load.
java.lang.UnsatisfiedLinkError: no opencv_java2411 in java.library.pathopencv_java2411

我不知道这是什么意思,有人可以帮忙吗?

您的集群节点上缺少 opencv。 有关如何处理此问题的所有详细信息,请参阅 here

长话短说,您需要在执行程序上安装 opencv。你不能真正以可移植的方式将它编译到你的工作的 .jar 中,因为它是 C 而不是 Java 代码。

更新: 请注意,Hadoop 执行程序上的环境由 hadoop-env.sh 设置。所以它需要包含一行:

JAVA_LIBRARY_PATH=${JAVA_LIBRARY_PATH}:/etc/opencv/lib
