百度了一下，衆說紛紜，大部分都不靠譜！
首先我這裏hive是裝好的，mysql也沒問題，今天換了一臺機器，拷貝系統後，啓動hive，hive啓動報錯！-------原因Hive啓動需要hive元數據庫初始化！！
在hive/bin 目錄下執行該命令---- ./schematool -dbType mysql -initSchema
如果執行不成功，你先講你的元數據庫刪除，或者是換一個源數據庫！
元數據庫地址：----------------------------------
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://node1:3306/hive_new?createDatabaseIfNotExist=true</value>
</property>
hive/conf中 hive-site.xml配置文件中，這裏 hive_new 就是你的元數據地址！
