hadoop - 错误 org.apache.hadoop.hdfs.server.datanode.DataNode : RECEIVED SIGNAL 15: SIGTERM

Question

在我的主节点中运行 Hive 查询时，我遇到了一些严重的问题。我有 3 个集群设置(1 个名称节点，2 个数据节点)。

版本:
Hadoop:2.7.3
hive :2.1.0
Java:openjdk 版本“1.8.0_111”
操作系统:ubuntu 16.04.1
环境:亚马逊 EC2

我已经在主节点中安装了 Hive，并使用 start-dfs.sh 和 start-yarn.sh 从主节点启动了所有守护进程。我检查了主节点和从节点中的所有守护进程，都运行良好。当我连接到 Hive 并运行示例查询时，主节点中的所有守护进程都停止运行，但数据节点中的守护进程仍在运行。请从 hadoop-hduser-datanode-namenode.log 中找到以下日志详细信息。
