error during job, obtaining debugging information... failed: execution error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.mapredtask

这个错误是在执行Hive任务时出现的，可能是由于MapReduce任务执行失败导致的。具体原因可能是多种多样的，需要查看详细的日志信息才能确定。建议检查Hadoop集群的运行状态，以及Hive任务的配置和参数是否正确。同时，可以尝试重新启动Hadoop集群和Hive服务，看是否能够解决问题。

Failed to startDockerApplication Container Engine

根据引用\[1\]和引用\[3\]的信息，"Failed to start Docker Application Container Engine"错误可能是由于修改docker的镜像源为国内镜像源后导致的。在引用\[3\]中提到，当尝试启动docker时，出现了"dockerd: failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: Iptables not found"的错误行。这个错误可能是由于缺少iptables工具导致的。

为了解决这个问题，可以尝试以下步骤：
1. 确保iptables工具已经安装在系统中。可以使用命令"sudo apt-get install iptables"来安装iptables。
2. 如果iptables已经安装，可以尝试重新启动docker服务。可以使用命令"sudo systemctl restart docker"来重新启动docker服务。
3. 如果问题仍然存在，可以尝试卸载并重新安装docker。可以使用命令"sudo apt-get remove docker"来卸载docker，然后使用适合你系统的方法重新安装docker。

希望这些解决方法能够帮助你解决"Failed to start Docker Application Container Engine"的问题。如果还有其他问题，请随时提问。
