This should be step 8, right?

 The spark access Unable to start Embedded Jetty Server is the same as an issue. Is there a solution to this problem  

 Zhi-yuan liu giving  

 peacewong@WDS 15:06  

Yes, it needs to be optimized. Can the boss help to raise a document PR?  

 peacewong@WDS 15:07  

Are there any other errors?  Or give the full stack  

 Zhi-yuan liu 15:21  

 @ peacewong @ WDS https://github.com/apache/incubator-linkis/issues/2762 I with this error  

 peacewong@WDS 15:34  

 I have a look at  

peacewong@WDS 15:40  

Is this CDH Spark on your side  

 Zhi-yuan liu double-break  

right  

 peacewong@WDS 15:41  

 

It is recommended to use Apache for Spark. CDH will introduce Jetty's underlying package and cause conflicts

peacewong@WDS 16:08  

 Can you debug it on your end?  You can see why the value here is not down  

peacewong@WDS 16:09  

 EngineConn test mode: wds-linkis.test.mode  

 peacewong@WDS 16:10  

 EngineConn If it is in test mode, it waits for remote debugging  

 peacewong@WDS 16:10  

Zhi-yuan liu, when  

 I get down  

 Zhi-yuan liu yet  

@peacewong@WDS Is the debug port number for remote debugging mandatory?  If I specify, change the linkis-CG-EngineconnManager?  

 peacewong@WDS 16:50  

 

It's the temporary directory from which you started it, engineconn.sh 刘志远  14:13







刘志远  14:13

这个应该是步骤8吧？




刘志远  14:56

大佬们




刘志远  14:56

spark访问 Unable to start embedded Jetty server，我看有一个Issues一样，这个问题有解决方案了么




刘志远  14:56







peacewong@WDS  15:06

是的，需要优化下，大佬帮忙提个文档pr？




peacewong@WDS  15:07

还有其他报错吗？或者给下完整堆栈下




刘志远  15:21

@peacewong@WDS https://github.com/apache/incubator-linkis/issues/2762我跟这个报错一摸一样




peacewong@WDS  15:34

我看看




peacewong@WDS  15:40

你这边是CDH的Spark吗




刘志远  15:40

对




peacewong@WDS  15:41

建议Spark用apache的版本，cdh的会引入jetty的底层包导致冲突问题




刘志远  15:41

[晕]




peacewong@WDS  16:08

你那边可以调试吗？可以看看这里的值为啥没有下




peacewong@WDS  16:09







peacewong@WDS  16:09

可以吧EngineConn的测试模式打开下看看：wds.linkis.test.mode




peacewong@WDS  16:10

EngineConn启动如果是判断测试模式会等待远程调试进行调试的




peacewong@WDS  16:10







刘志远  16:11

我弄下




刘志远  16:47

@peacewong@WDS 这个远程调试的debug端口号是必须指定么？我指定的话是改linkis-cg-engineconnmanager里面的？




peacewong@WDS  16:50

是改启动的那个临时目录来着engineConn.sh
