Question

我是hive的新手，当我尝试在配置后启动配置单元时，出现了问题。我完全迷失了。有人可以帮忙吗？

首先检查你的hadoop是否处于运行状态。还要检查你的hive-evn.sh并在hive-env.sh中设置JAVA_HOME，HADOOP_HOME和hive路径（如果不存在）。然后从蜂巢终端执行配置单元。还要在.bashrc中添加JAVA_HOME，HADOOP_HOME，HIVE_HOME。

如果上述情况不起作用，那么：

默认情况下，hive使用derby数据库存储元表。在metastore_db下，将创建两个锁定文件dbex.lck和db.lck。作为一种解决方法，只需重命名这些2 * .lck文件并尝试再次从控制台执行配置单元。看它是否有效。
