Hive Derby 元存储配置

Question

我已经使用 tutorialspoint 配置了我的 Hive Over Hadoop 和 Hbase http://www.tutorialspoint.com/hive/hive_installation.htm 面对 HIVE 的这个问题。请帮忙

Answer 1

Derby Server 没有运行。所以它会抛出连接被拒绝的异常。

转到 %DERBY_HOME%\bin 和 StartNetworkServer.cmd 文件

现在重启 hive 服务。

希望对你有帮助

Answer 2

您似乎还没有启动 Derby 数据库。看看这个 Hive 文档：https://cwiki.apache.org/confluence/display/Hive/HiveDerbyServerMode。关于如何开始德比有一个简短的段落。
