Hive报错:HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.me

想学习架构师构建流程请跳转：Java架构师系统架构设计
启动hive的metastore或者启动hive后执行命令报错如下：

FAILED: HiveException java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.me
1

原因分析：
是由于没有初始化数据库导致，执行名称初始化数据库即可。

解决办法：
执行命令：schematool -dbType mysql -initSchema

注意：我这里hive的metastore数据库为MySQL

[oldlu@bigdata-training hadoop-2.6.0-cdh5.7.6]$ schematool -dbType mysql -initSchema
