在运行

#数据库的初始化。
     bin/schematool -initSchema -dbType mysql

报错

*** schemaTool failed ***

在执行 mysql -hlocalhost -uroot -p
报错ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
判断是由于mysql远程登录的问题造成的

参照http://jingyan.baidu.com/article/636f38bb21d883d6b946106f.html

问题解决

在执行初始化命令时，如果遇到下开错误

Error: Duplicate key name 'PCS_STATS_IDX' (state=42000,code=1061)
org.apache.hadoop.hive.metastore.HiveMetaException: Schema initialization FAILED! Metastore state would be inconsistent !!
Underlying cause: java.io.IOException : Schema script failed, errorcode 2
Use --verbose for detailed stacktrace.

可以先停止mysql服务，再执行初始化命令
