Zeppelin Oracle SQL 查询优先运行
我正在尝试使用 Zeppelin(Windows 10 上的 v 0.7.0 java 1.8；与 docker<相同)/a> 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，我已经找到了诸如 example 之类的论文.我尝试使用 jdbc 解释器:
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
连接看起来已成功建立*，但即使是最简单的查询(如sql% select 1 from dual)也会永远运行.
Connection looks to be established successfully*, but even simplest query (like sql% select 1 from dual) runs for ever.
有人知道/知道要添加什么吗?
Does anyone knows/have a clue on what is to be added?

与此同时，我在使用带有 Scala 的 spark 解释器而不是 jdbc 相同的驱动程序时没有问题.
In the same time I don't have an issue using spark interpretor with scala over jdbc same driver.
- 至少当我提供错误的密码时，它会打印出有意义的响应
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
不是有效的 SQL.
在 gv$session 中检查 Oracle 端的查询.如果它正在运行，它就会在那里.
Check on Oracle side in gv$session for your query. If it is running, it will be there.
