Failed to connect database

[zoey224]

**问题描述：登陆后无法连接上数据库

**已尝试解决方法：

已在 ${LINKIS_HOME}/linkis-metadata/conf/linkis.properties中添加了Hive meta信息，如下：
##datasource
wds.linkis.server.login.use.default=false
hive.meta.url=jdbc:mysql://127.0.0.1:3306/hive?characterEncoding=UTF-8
hive.meta.user=xxxx
hive.meta.password=xxxx

**查看日志
${LINKIS_HOME}/linkis-metadata/logs/linkis-metada.out

ERROR (main) ERROR DruidDataSource - mysql should not use 'PoolPreparedStatements'
