解決 message:Hive Schema version 2.1.0 does not match metastore's schema version 1.2.0

hive啓動時遇到問題

Caused by: MetaException(message:Hive Schema version 2.1.0 does not match metastore's schema version 1.2.0 Metastore is not upgraded or corrupt)

解決辦法：

$HIVE_HOME/scripts/metastore/upgrade/mysql 路徑下提供了一些sql腳本執行升級，

mysql -uroot -p

mysql> use hive;
Database changed
mysql> source upgrade-1.2.0-to-2.0.0.mysql.sql
mysql> source upgrade-2.0.0-to-2.1.0.mysql.sql

從新啓動hive便可。
