问题描述
我正在尝试使用Zeppelin(Windows 10上的v 0.7.0 Java 1.8;与 docker v .0.7.1)用于查询Oracle数据库的JDBC解释器.
I am trying to use Zeppelin (v 0.7.0 java 1.8 on Windows 10; same with docker v .0.7.1) JDBC interpreter to query Oracle Database.
到目前为止,我已经找到了示例之类的论文.我尝试将jdbc解释器用于:
So far I've found papers like example. I try to use jdbc interpreter with:
common.max_count=100
default.driver=oracle.jdbc.pool.OracleDataSource
default.password:$password
default.user=$my_user_name
default.url=jdbc:oracle:thin:@$host:1521/$service_name>
zeppelin.jdbc.concurrent.max_connection=10
zeppelin.jdbc.concurrent.use=true
连接似乎已成功建立*,但即使是最简单的查询(如sql% select 1 from dual
)也将永远运行.
Connection looks to be established successfully*, but even simplest query (like sql% select 1 from dual
) runs for ever.
有人知道/对要添加的内容有任何线索吗?
Does anyone knows/have a clue on what is to be added?
我在终端中看到的内容-重复行
what I see in terminal - repeating lines
与此同时,在jdbc相同的驱动程序上使用带有Scala的Spark解释器时,我没有任何问题.
In the same time I don't have an issue using spark interpretor with scala over jdbc same driver.
- 至少当我输入错误密码时,它会显示有意义的响应
推荐答案
您确定查询正在运行吗?
Are you sure a query is running?
selec 1 from dual
无效的SQL.
在gv $ session的Oracle端检查您的查询.如果它正在运行,它将在那里.
Check on Oracle side in gv$session for your query. If it is running, it will be there.
