Error: Duplicate key name 'PCS_STATS_IDX' (state=42000,code=1061) ----Hive schematool -initSchema

当我们输入./schematool -initSchema -dbType mysql的时候，会出现以下错误

Metastore connection URL: jdbc:mysql://192.168.*./hive?createDatabaseIfNotExist=true

Metastore Connection Driver : com.mysql.jdbc.Driver

Metastore connection User: hiveuser

Starting metastore schema initialization to 2.1.0

以上错误查看mysql是否已经创建了hive这个表, 如果创建，你想从新安装的话，把那个你创建的表删了即可。
