当我尝试在emr集群上运行hadoop作业时，我得到了下面提到的错误，因为“AM Container”导致无法启动，并且在查看容器日志时，我发现它失败了在启动“MRAppMaster”时。在本地开发人员桌面上，我能够成功运行该作业。
我在网上搜索并找到了这个（Hadoop 2.6.0: Basic error "starting MRAppMaster" after installing），其中说这个问题可能是因为有多个版本的hadoop“hadoop.so”。根据堆栈中提到的建议，可以获取“java.library.path”和我的结果： ：/ usr / lib中/ Hadoop的LZO / LIB /天然：/ usr / lib中/ hadoop的/ LIB /本地 路径：/ usr / lib / hadoop-lzo / lib / native，不包含任何hadoop.so文件。 路径：/ usr / lib / hadoop / lib / native，确实包含hadoop.so和hadoop.so.1.0。
我尝试从后面删除一个并运行我的工作，但它继续失败并出现同样的错误。
