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?

我在终端看到的 - 重复行

what I see in terminal - repeating lines

sKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbcDEBUG [2017-06-15 16:03:28,203] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbcDEBUG [2017-06-15 16:03:28,204] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbcDEBUG [2017-06-15 16:03:28,204] ({Thread-90} InterpreterFactory.java[getInterpreterSessionKey]:1244) - 解释器会话密钥:shared_session,注意:2CMEC9SS4,用户:匿名,解释器设置名称:jdbcDEBUG [2017-06-15 16:03:28,205] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbcDEBUG [2017-06-15 16:03:28,205] ({Thread-90} InterpreterSetting.java[getInterpreterProcessKey]:143) - getInterpreterProcessKey: shared_process for InterpreterSetting Id: 2CMBZV4T1, Name: jdbc

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.

这篇关于Zeppelin Oracle SQL 查询优先运行的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
