HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.S
项目场景：
启动mysql后 启动hive,执行 show databases;后出现以下问题。或者在show databases时候报错：Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
在跟着尚硅谷数仓4.0视频学习的时候，所有都是按照视频中配置，hadoop版本为hadoop3.1.3,hive版本为hive3.1.2。之后就遇到了再启动hive服务之后，使用show databases,报错Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient。网上有视频说是hive的元服务没启动，使用hive --service metastore &启动元服务之后又报错：org.apache.hadoop.conf.Configuration.getPassword(Ljava/lang/String；)[C。
最后把hive版本降到了2.3.9成功解决以上的两个问题。
hive2.3.9可以去清华大学开源软件镜像站自己手动下载，地址链接：https://mirrors.tuna.tsinghua.edu.cn/apache/hive/hive-2.3.9/
问题描述
FAILED: HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
原因分析：
该错误表明无法初始化元数据存储客户端的会话对象，即无法访问Hive元数据。
解决过程：
metadata服务开启
Hive的metadata服务未开启导致的。
解决办法：
进入到Hive的bin目录下,键入命令:
报错

解决新方案
把hive版本降到了2.3.9成功解决以上的两个问题。
hive2.3.9可以去清华大学开源软件镜像站自己手动下载，地址链接：https://mirrors.tuna.tsinghua.edu.cn/apache/hive/hive-2.3.9/
安装hive->配置环境变量->修改jar包冲突 -> 初始化元数据
